Questions
Frequently asked
What's the difference between a multicooker and a rice cooker?
A multicooker is a pressure-capable, do-many-jobs appliance — it pressure-cooks, slow-cooks, sautés and often makes yogurt. A rice cooker does one thing extremely well: cook rice, and usually steam. If rice is most of what you want, a dedicated rice cooker tends to cook it better; if you want one machine for stews, beans and rice, a multicooker is the flexible choice.
What is an electric pressure cooker, and is an Instant Pot one?
Yes. An electric pressure cooker seals a pot and raises the internal pressure so water boils hotter than 212°F, which cooks food faster. An Instant Pot is a brand of electric pressure cooker that also bundles slow-cook, sauté and other modes, which is why it is usually called a multicooker. Our top picks are here.
What is sous vide?
Sous vide (French for “under vacuum”) means sealing food in a bag and cooking it in water held at a precise temperature, often for hours. An immersion circulator clips to a pot, heats the water and keeps it moving so the whole bath stays at, say, 130°F — giving you edge-to-edge doneness you cannot overshoot. More on sous vide here.
Do I need a special container for a sous vide circulator?
No — any pot deep enough to submerge the circulator to its minimum water line works. A lidded plastic container cuts evaporation on long cooks, but it is optional. Check the maker's stated minimum and maximum water depth. See our recommended machines.
Is a Zojirushi rice cooker worth it?
For someone who eats rice often, usually yes. Zojirushi's fuzzy-logic models adjust time and temperature to the rice type and hold it at serving temperature for hours without drying it out, which a basic on/off cooker cannot. Whether it justifies the price depends on how much rice you cook — we set it against cheaper models on the best rice cooker page.
What's the difference between a multicooker and a slow cooker?
A slow cooker cooks low and slow at ordinary pressure over many hours. A multicooker can do that same slow-cook job but also pressure-cook the same dish in a fraction of the time. If you only want set-and-forget over a workday, a standalone slow cooker is cheaper; a multicooker buys you the fast option too.
Can a multicooker replace my rice cooker?
For occasional rice, yes — most multicookers have a rice setting. For daily rice, a dedicated fuzzy-logic rice cooker generally gives more consistent results and a better keep-warm, because that is the only job it is tuned for.
Ninja Foodi vs Instant Pot — which should I get?
They overlap heavily as pressure-capable multicookers; the practical split is the second function each one bundles and the pot design. We rank them on the same five published metrics rather than on marketing, so the answer comes down to which extra modes you will actually use. Our multicooker roundup weighs them up.
Is a fuzzy-logic rice cooker better than a basic one?
For results, generally yes. A basic cooker switches off when the water is gone; a fuzzy-logic (micom) cooker measures temperature and adjusts the cook to the rice, then holds it warm without turning the bottom to a crust. A basic cooker is fine for plain white rice on a budget. The rice cooker hub covers the trade-off.
How much electricity does a pressure cooker use?
Less than most people assume, because it only draws full power while coming up to pressure. At the US average rate of 18.83¢ per kWh, a 1,000-watt cooker run flat-out costs about 18.8¢ an hour — and it is not at full draw for most of that. We show the arithmetic on every pick. Here is the method.
Are electric pressure cookers safe?
Modern electric pressure cookers have several interlocks — a lid that will not open while under pressure and will not pressurize unless sealed, plus an over-pressure release. They are far harder to misuse than the stovetop models people remember. Follow the manual's minimum-liquid and maximum-fill lines.
What size multicooker should I buy?
Match it to your household: a 3-quart suits one or two people, a 6-quart is the common family size, and an 8-quart suits batch cooking or larger groups. Bigger is not automatically better — a half-full large pot takes longer to come to pressure. The multicooker hub goes into sizing.
Do sous vide machines use much power?
A circulator draws its rated wattage only to bring the water up to temperature; once there it just tops up heat now and then, so a long cook uses far less than rated watts times hours would suggest. An insulating lid or a covered container lowers it further. We compute it at the rated draw as an upper bound.
Can I make yogurt in a multicooker?
Many can — a dedicated yogurt setting holds milk at the low, steady temperature culturing needs. If that matters to you, confirm the specific model lists a yogurt function, because not every multicooker includes one.
Do you test the machines?
No — and we say so plainly. There is no test kitchen here; machines we claim to have tested: 0. What we do instead is compile every published specification, cite it, do the running-cost math, and summarize attributed owner sentiment. Our full method is here.
How current are the prices?
They are pulled live from Amazon and stamped with the date they were last checked. If that data goes stale, the number disappears and the button says 'check price' — we never show a hand-typed or out-of-date price. Prices change, and Amazon's price at checkout is the one that counts.
How do you pick what to recommend?
Every machine is scored on five published metrics — Capability, Capacity, Documentation, Build and Value — all judged from the manufacturer's own documents. Picks are chosen buyer-first and are independent of any commission. The rubric is published in full.
How do you make money?
Affiliate commissions: we earn from qualifying Amazon purchases made through our links, at no extra cost to you. It does not decide our rankings. Full disclosure here.
Why does a product on your site have no running-cost figure?
Because its manufacturer publishes no wattage anywhere we could cite, and we will not guess one or borrow it from a similar model. The gap is the honest answer, and we show it rather than fill it in.
