equipment. Steamer with silicone legs.

Visual inspection: the surface of the multicooker is glossy plastic, without burrs and large gaps between the parts, well assembled, the lid is non-removable, quietly and smoothly leans back. The rear legs are rubberized, the power cord is white (which is very nice), it fits into the connector on the case. The buttons are tight - you need to make an effort to press them. A battery powered clock is ticking on the screen. The smell is standard, like from any new technology: a little rubber, a little plastic, but not harsh. On the lid there are silicone gaskets for the pan and valve. The latter is simply stuck into the hole in the lid, it is disassembled for washing, but with great difficulty.
How to disassemble the valve: in the photo "bottom view" you can see two hieroglyphs and an arrow "tudy-syudy", next to the left hieroglyph there is a tiny triangle - turn the large triangle squeezed out on the spherical part of the valve in its direction and pull both parts in different directions. In my valve, the parts fit very tightly to each other, so I had to carefully pry the spherical half in a circle with my nails, twist and pull. While the Big Triangle does not stand opposite the left hieroglyph, the lock will be closed. The lock itself is standard: it consists of L-shaped recesses into which three protrusions enter, located along the perimeter of the valve with a step of 120 degrees (the first protrusion is on the opposite side of the large triangle).
Saucepan inside and outside covered with a black rough non-stick coating, wall thickness 1.5 mm, weight 299 g (+ -1 g). The coating is not scratched with a fingernail, water drops from it. A bowl filled to the brim holds a little over 3000 g of cold water, which corresponds to a volume of 3 liters. On the lateral surface, volume marks are extruded, which do not pretend to correspond to reality. To the lower risk, 500 g of water is poured, to the upper mark about 2200 g of water.

When off, the display shows the current time, when on, the orange backlight comes on. During operation, the indicator "a la bowl" is displayed with a running line of either peas or rice that appears above it. The Delayed start function is implemented through the Preset button as in an alarm clock: you need to set the hours and minutes (in 10 minute increments) by absolute valuerather than relative. That is, you need to get the porridge by 7:30 in the morning, set it at 7:30, regardless of the current time. If a function is unavailable in the selected mode (for example, delayed start or cooking time), pressing buttons with unavailable functions will be ignored.If in the selected mode it is possible to set the cooking time, the Timer indicator lights up. The settings are reset with the Heat / Off button.

* Warming up - it is either on or not. The display shows 0:00, and then will show the time in hours and minutes since the start of heating.

First run: "Steam cooking" mode.
First, the cooking time cannot be set to less than 30 minutes. Water (3 multi-glasses) boiled after 6 minutes and steam poured out of the valve.
Secondly, when condensate collected in the valve and blocked the holes, the multicooker began to sing! The sounds emitted were very reminiscent of the chirping of birds on the first warm spring day. If you block the steam outlet, then it begins to seep out from under the lid.
Thirdly, the first 10 minutes of work there was a rather unpleasant smell of burnt rubber, but then it disappeared. Now it doesn't seem to smell.
Fourthly, if you inaccurately open the lid, and it opens by pressing the silver button, you will get a cloud of hot steam right on your hand. Just be careful for those who are used to multicooker that opens by the handle on the lid.
Fifthly, when opening the lid, she made a puddle ... there is no water-collecting reservoir, there is only a rim along the upper perimeter of the MB and around the hole for the bowl. The edge of the bowl itself is made without a bend to the bottom (as on ordinary enameled pots), which can, theoretically, lead to the escape of the porridge onto the heating element.
And - most importantly - the countdown begins at once, and not from the moment the water boils. At the end of the program, there will be three quiet short pee pee.
first turn on and first surprise

Second run: "Porridge" mode.
Buckwheat porridge: 1 multi-glass of cereal = 140 g or about 180 g of water. Poured 2 glasses of cereal and 4 water. The "bowl of peas" icon appears and disappears with an interval of 1-2 minutes, its appearance / disappearance coincides with the clicks of the relay. It's a pity that I didn't notice how long the porridge was cooking, but I noticed that at the end of the program, instead of the clock, a countdown was displayed. At the time of detection, it was 0:05, and the Timer indicator light up above the display. The porridge turned out well boiled, crumbly (not smear), nothing ran away and did not burn. Cools down. During cooking, the multicooker smelled only of porridge.

Third run: Standard mode.
I decided to check how the delayed start works. It was recommended to cook a small amount of cereals on the "Fast" mode, so 1.5 MB-glasses of millet groats and 3 glasses of water (+ salt) went into the pan. Otherwise, we don't have time to eat So, in this mode there is no delay, pressing the buttons did not change anything. Then I chose the "Standard" mode, using the buttons Preset, Hours, Minutes set 7:00. In the morning, after the alarm went off, I ran to the kitchen: the Heat indicator was on and the display was at 0:15. It turns out that MV began to cook, found that there was little porridge and completed the program 15 minutes ahead of schedule. Smart saucepan. The porridge turned out to be normal, but next time I will reduce the amount of water so that it does not boil so much.

Bakery products: Pie mode.
Baked according to your recipe

(Advertising: first time bought in an online store 🔗... The ordering process, the promptness of the response and the speed of delivery were pleasantly pleased Not even 2 days had passed since the MV was brought from a warehouse in Moscow.)

This comment is not quoted - it is for technical purposes.
Truncated, there will be no kinetics .... for the repair of a broken camera, the price was turned down, exceeding the cost of a good 12MP camera.I will fix it (as usual) on my own, but I would only find time.

If you have any questions - ask. I will measure, check, weld.

Ossachka, I sympathize about the fotik.

Hello everyone! I'm new among you. For a very long time I chose MV for myself, read your advice and finally bought today MV SUPRA MCS-4531. I haven't cooked anything yet, while I'm getting to know her. I have a question. A steamer rack on small legs, and how much water you need to pour so that it does not boil away. In general, there is very little information on this model. So I'll bore you if no one objects.

A steamer grate with small legs, but how much water do you need to pour so that it does not boil away?

Welcome to the forum!
To be honest, I haven't measured it yet. 3-4 glasses from the set are enough for the "30 minutes" program of steaming, about 1.5-2 glasses remain. Tomorrow I'll boil eggs, see how much evaporates
Now I park for study, so I often drive a large multicooker, which is more familiar to me. So let's deal with Supra together, the instructions for it are really useless.

Thank you very much for your reply! I asked for information, I don't think I will use it often, because the grill is not comfortable (large holes and straight, not a bowl). Small vegetables will fall through or fall out when removed. I wonder if a bowl from some other model won't fit it?

To the previous message: a saucepan + a double boiler + water + 5 eggs = 1274 g. I poured water 535g (3 full multi-glasses), put it on the Steamer mode for 30 minutes, after 7 minutes the heating element turned off, which means it boiled. She boiled the eggs for exactly 10 minutes, after which she weighed it - it became 1200 g. Considering that the steam poured out of the valve 6-7 minutes after turning on the multicooker, you can calculate the average evaporation rate - 7.5 g of water per minute
I can try on a steam boiler from Panasonic on the 10th in the store, or ask on the forum if someone is running into the kitchen with a centimeter right now. I think you can adapt a silicone colander for a double boiler, but except on the Internet I have not seen such.

I decided to cook liquid rice porridge. washed and poured out 0.5 cups of rice, 1 glass of milk, 1 glass of water, salt, sugar. I turned on the porridge mode. After 22 minutes, bubbles came out of the valve (apparently in this mode there is a strong boiling), so after waiting 5 minutes, I turned it off. In general, the rice was cooked almost, it would have been 5 minutes and it would have been good in general. But ... what mode to cook, if you need a delayed start. And I'll see a silicone colander in the store, maybe we have it. Thanks for the tip !!!

Something happened today with a misfire with the Kas regime. 3 multi-glasses of different cereals + 6 multi-glasses of water = well-cooked porridge, floating in water I put the porridge-soup on Standard, I'm waiting ... Yesterday I successfully cooked it from 2.5 cereals and 5 water (though, to boil the barley, I first cooked a little on Slow cooker so that there is not a lot of foam). Apparently, I overestimated the "mental" capabilities of this multi. Nothing of the kind happened to Panas over the course of a year - it will puff for at least 1.5 hours, but it will cook, and Supra has a tendency to cook everything for 40 minutes. Or she really calculated for small volumes.

I tried to cook porridge in the slow cooker mode, the result is the same, there are bubbles. Today I cooked little rice on the mode, everything too. I will experiment more, then unsubscribe. And for a double boiler, I bought a plastic plate that fits perfectly to the diameter of the saucepan, drilled holes, and it turned out to be a double boiler.

Wasp, I also looked at this slow cooker in the store today, and then came home and saw the Temka. It seemed to me that the saucepan was very thin and light, but outwardly very pretty, so I went to touch it with its handles and look at it in full size. Congratulations on your purchase.

Congratulations on your purchase.

Thank you! And you with your name day
For comparison, the pan of Panasonic of the 18th weighs 400g, against the Suprovskaya 300-gram one I also found disadvantages: either my water is hard or after the Steamer scale forms The first time it did not wash, I poured warm water and threw a few grains of citric acid,left for a couple of hours - the white stains dissolved. And the pan was a little scratched from the bottom of the heater, but it's my own fault - out of habit, I twisted it to make it sit tighter.

Something happened today with a misfire with the Kas regime.

The reason was found and eliminated: the washed fine cereal absorbed almost 100 ml of water! When pouring liquid, I "by eye" took into account only 50g (this was the case for coarse-grained cereals). Moral: you need to weigh the groats before and after washing.

Weighed the bowl in our, Lena, little librarian, as much as 471g!
Outwardly, I also VERY liked it, but here's the cup ... And is this beauty worth a gallop?
I like the little dumplings!

Judging by the Yandex market 1 999 ... 3 199 rubles. But since I could not order it anywhere for a whole month, I had to arrange delivery from a neighboring village - it turned out a little less than 2500 rubles.

Girls, hello! I stare at this beauty. Fell in love at first sight, although I understand that 3 liters will probably not be enough. I have a question for you. How do you manage to delay milk porridge?

I haven’t cooked on a delay yet. Tomorrow I'll try to cook millet, I'll write how it turned out. Rice on porridge on the delay will not work, since the milk boils strongly. Must try on soup. I bake rye-wheat bread in it, I like it. Cakes too. The stew turns out to be very tasty, soft. If the family is not big. then 3 liters is enough.

Thank you. I think it still has a lot of power. If you look by analogy with Panasonic 10 and 18, a small Panas has a third less power than a large one. And this suprochka, on the contrary, has even more than a 5-liter one. So I doubt - that suddenly it will overheat in all modes ...

And I like the heating rate! He bakes muffins perfectly, and frying for soup can be done in 5-10 minutes. Eggs also cook quickly. Small but powerful, I don't need a pressure cooker with it

Wasp, how are things going with milk porridge? And does it not burn?

And another question. Maybe I missed it, then sorry. What is the diameter of the bowl. What is the size of the baked goods?

Wasp, how are things going with milk porridge? And does it not burn?

I don't like dairy products, the exception is buckwheat with milk and semolina. I cook semolina as in an ordinary saucepan on the stove, stirring (I hate lumps!), The milk does not burn at all, I have cooked it several times in the Steam Cooker (10-12 minutes and you're done!).

What is the diameter of the bowl.What is the size of the baked goods?

I ran to measure: the height of the bowl is 11.2 cm, the upper maximum outer diameter (together with the rim) is 21.2 cm, the upper inner is 19.2 cm, the lower outer is 14.5 cm (this is measured by the flat part of the bottom), and so a saucepan with vertical walls 19.2 cm in diameter from top to bottom, only at a distance of 2-2.5 cm from the bottom begins to round out to 14.5 cm. I wrote about baking here: Zebra cupcake I also tried mini-muffins 3-4 cm high and large ones - 6-8 cm, the center is baked well. I bake often, there are no complaints, only the Pie must be turned on twice if something above 4 cm is baked. If you rub a cold bowl with margarine, then the baked goods will come off when you pry them with a spatula.

Thank you very much for the detailed answer !!

Girls, pliz, can anyone cook milk porridge with a delay? Doesn't run away?

Girls, pliz, can anyone cook milk porridge with a delay? Doesn't run away?

I wrote about rice porridge, it runs away from me, but I read it from girls. they smear around with oil and write. that doesn't run away, though I haven't tried it. I also read that they cook soup on the program. But I tried to cook millet porridge with a delay, everything works out, the porridge was cooked, nothing escaped, it was very tasty. I tried to cook rice porridge on the soup program, but put a plastic plate on top, which I adapted for a double boiler. So she doesn't run away. On porridge, the program lasts 45 minutes, of which he actively cooks 35 minutes, and then stands on the heat for 10 minutes.
Wasp, I want to ask you, how does MV work for you in automatic modes? I have 35 minutes on the pie, of which 15 minutes on the display the current time, and then the timer for heat turns on, with a countdown for 20 minutes, on porridge the same thing, only 35 minutes on the current time and 10 minutes on the timer. I have not tried the rest of the programs yet.

Tell me how to insert a photo? I would show my steamer tray, in case someone comes in handy.

[where to put onions from the marinade for barbecue]

How does MV work for you in automatic modes? I have 35 minutes on the pie, of which 15 minutes on the display the current time, and then the timer for heat turns on, with a countdown for 20 minutes, on porridge the same thing ...

I also have a program on Pie running for 35-38 minutes (until wee-wee-wee), there is a countdown, but I don’t know how long it starts, I saw that 0:18 showed. During the countdown, it does not switch to Heat, the Start indicator is on. Panas behaves the same way, so I didn't pay much attention

Thanks for the pictures! I will look for such a deep plate.

Found the answer to the question "where to put onions from the marinade for barbecue"?
The other day I got a saucepan with such onions. A lot of onions, it's a pity to throw them away ... I read on the internet that Brown Rice (Baked Rice) is an analogue of Frying at Supra. I put 2 cm of onion (without liquid), a couple of tablespoons of sunflower oil, a few diced potatoes, and salt in a saucepan. Included on Baked Rice ...the onions are burnt! I flew in to the smell, mixed, put on Stew for 30 minutes, so that the potatoes were cooked. In general, the dish turned out to be nothing, but nuclear-peppery. The rest of the onion was washed a little from the pepper in colander and tossed in with new potatoes, salt and chopped, it is not clear where it came from, a stub of carrots in Panas on Plov. I remembered that I also poured a few spoons of water into it so as not to leave the bottom of the pan uncovered. It turned out wonderful! Fragrant potatoes in mashed potatoes with spices

During the countdown, it does not switch to Heat, the Start indicator is on.

I got confused, it’s not heat that comes on, but a timer and two start and timer lights are on. And about baked rice, it turns out that it warms even more than stewing? I read it on a multicooker. ru probably your answer is that fry on stewing, I tried, for sure, it turns out better than on a pie, and you can set the time as much as necessary. You need to try on baked rice as it turns out. And yet, on what mode did you try to cook pilaf? And then I cooked it, I don't remember on what mode, so my rice is boiled like porridge. True, I cook pilaf with round rice, but on the stove I get it crumbly. My husband did not like it, rejected it! I am not experimenting with pilaf anymore.

I, too, now have such a slow cooker, I haven't really figured out what's what yet)

I also have such a slow cooker now

Congratulations! The first tip - when you cook something and take out the bowl - do not lower the lid. "Smart" developers have made it so that a few drops of water can fall from the valve onto the heating element (spots will appear) or directly onto the sensor button in the center

thanks for the advice
The only thing I do not like (so far) is the instruction, it is not really clear what the difference between the modes is.
Baked glutinous rice ..

[Standard]

I do pilaf on Standard, soup and compotes - on Supe, baked goods on Pie (I think I always run the program 2 times in a row). FROM Slow cooker I misunderstood something, probably the temperature is low there, it is better to use the mode Extinguishing - then it will definitely not remain raw. On mode Little rice a couple of times the error "overheating" popped up, on Baked rice really fries the crust, on it you can fry mushrooms and onions or fry for the first courses. I didn't see the difference between the other "rice regimes", probably, the Chinese know better

A Glutinous rice Now I'll go and try it, probably there will be a mess.
I tried: 2 multi-cooker glasses of wheat groats for 4 glasses of water + salt, cooked for about 50 minutes. It looks like porridge with not completely evaporated water, a little sour. Cools down.

Hello! Girls, please tell me, I bought a Supra multicooker, and where is her pilaf mode, I can't figure it out? I decided to cook on the Slow Cooker mode. Here I sit, waiting for what happens

[Standard]

There is no pilaf in Panasonic, but in Supra or on Standard cook or on Baked rice - then the bottom, as with Panasonic, will fry a little after boiling water, but the onion may burn at the same time.You can reset the Slow Cooker program by pressing Heat-Off and cook in another mode (where the time is not set manually) - the multicooker will automatically detect that the water has evaporated, squeak about readiness and will not spoil the dish. I do this sometimes: I cook for Standard, and then (for the bottom crust) I put on Steamer or Pie literally for 2-3 minutes.

Pilaf waited. I cooked on the "Slow cooker" mode for 1 hour 30 minutes. I took 200 grams of pork and 1.25 measuring cups of rice, 2.5 measuring cups of water. It turned out pretty well. You just need to reduce the cooking time to 1 hour, and the rice has dried a little from the bottom to the bottom of the saucepan, but not burnt. Rice boiled well, but not very crumbly. It tastes great.

thanks for the advice

The instruction is about nothing at all. That she is, that she is not. Nothing is really painted.

Happy first pilaf! The instruction is really no. If Supra were my first slow cooker, I would be at a loss ... and so I slowly master it "by typing"

Thank you!!! And the pilaf went off with a bang, they ate it all, now I regret that I cooked little, I was afraid to pour a lot for the first time !!! I have my first slow cooker in my life, I think that with the help of this site I can handle it too. Thank you for your support !!!

I also have my first multicooker in my life, it's still so scary to use it, while I actively use the stewing mode and there is not enough rice

Now I'm cooking corn porridge, the cartoon also "sings"

The people and from the Supra 4511 recipes according to what principle should they redo - proportionally reduce the volumes? And what happens with time? write a little more - never used multicooker.

yesterday I made potatoes with creamy sauce in a slow cooker ... it turned out to be a fabulously delicious dish !!!!! Made in the "slow cooker" mode. I am slowly mastering this thing. In principle, the thing is very good ... while I like it

Hello girls! I also bought this wonderful device. Prepared borscht and buckwheat porridge. I started to cook a casserole and this device gave me an E3 error ... hurt yourself ... I dragged him back to the store, poured water on the pie ... it works ... and I was baking a casserole in the oven. So what to do now, they returned it to me, they say either send it to the service center for 21 days or take it back ... Try it again, translate the products ... no one had such an error? I read what it means according to the instructions, the upper or lower sensor is not working properly ...
