COSORI CMC-CO601-SUS 6 Qt 9-in-1 Pressure Cooker: features and specs

The COSORI CMC-CO601-SUS is a 6-quart electric pressure cooker that also works as a slow cooker, rice cooker, steamer, sauté pan and sous vide unit. It is meant for kitchens that want one counter appliance to handle stews, grains and beans. Here is what its features mean and what to check for your household.

What "9-in-1" covers

COSORI lists pressure cooking, rice, steam, sterilize, oatmeal/porridge, stew/broth, bean/grain, meat/poultry, slow cook, sauté, ferment, sous vide and keep warm. The "9-in-1" label is the brand's own count of the functions. In general, a pressure cooker raises the boiling point of water in a sealed pot, so food cooks faster than in an open pot, which is why beans and tougher cuts suit it.

Sous vide cooks food in sealed bags at a low, steady temperature. Sauté lets you brown food in the same pot before pressure cooking, which saves a pan.

Capacity and power

The cooker holds 6 quarts (about 5.7 litres) and draws 1100W on a 120V supply. The inner pot measures 9.41 x 9.41 x 6.18 inches, with an inner diameter of 8.66 inches. The whole unit is 13.4 x 12.6 x 12.5 inches and weighs 11.9 pounds, so it is a counter appliance, not something to carry lightly. A 6-quart size generally suits a household of about two to five people.

Venting design

COSORI puts the Seal/Vent button away from the steam release valve, and angles the steam release 30 degrees backward. The aim is to move steam away from the user when venting. The brand also advises that very liquid recipes, like soups and stews, can splatter on quick release. It suggests releasing steam naturally for those. Read the manual's release guidance, as the lid should only be opened after the float valve has dropped.

Lid, pot and safety features

Closing the lid means lining up the orange dot on the lid with the dot on the base and twisting clockwise. The inner pot has an anti-spin design, so it stays put while you stir during sautéing.

COSORI lists 12 safety features, including a double-layer anti-scalding lid and overheat protection. As with any pressure cooker, follow the manual on liquid minimums, fill lines and venting.

Pot material and cleaning

The aluminum inner pot has a ceramic nonstick coating that COSORI describes as BPA-free for food contact. The housing is fingerprint-resistant stainless steel, and the lid, inner pot and accessories are listed as dishwasher-safe. A 0.5-inch wider gap around the pot is meant to make cleaning easier. Replacement parts, such as the inner pot and sealing ring, are sold separately, and COSORI advises against using a non-COSORI inner pot in this model.

Display, app and recipes

A progress bar on the display shows the cooking stage. A recipe book is included, and more recipes are available in the free VeSync app.

What is in the box

The listing names the 6-quart cooker, inner pot, steam rack, recipe book, user manual and quick reference guide.

Who it suits

It suits home cooks who want one appliance for batch cooking, rice and slow-cooked dishes, and households short on cupboard space for separate pots.

What to check before you buy

• Size: measure the counter and the cupboard height, including headroom for the lid.
• Capacity: decide whether 6 quarts fits your usual batch size.
• Power: confirm a suitable 120V outlet is within reach.
• Upkeep: check how often the sealing ring needs replacing and where to get one.
• Cleaning: confirm which parts can go in the dishwasher.
• App: decide whether you want to use VeSync, as the unit works from its own controls.
