Instant Pot Duo vs Duo Nova: Which is Better? If you’re a fan of the ‘set it and forget it’ style of cooking, the handy keep warm function means your food won’t go cold if you do actually forget about it. The delay start button allows you to postpone cooking for up to 24 hours, but be sure not to leave anything perishable in the pot if you’re using this function. It comes with a steam rack, but this is only really useful for larger foods, smaller vegetables will fall straight through the rack into the water below which is frustrating. With a familiar design, the Duo Nova is instantly recognizable as an Instant Pot and as we’ve said in previous reviews, multi-cookers are not the most attractive of the kitchen counter appliances. Some of the design requirements of pressure cookers almost inevitably lead to some cleaning challenges. However, the DUO Nova navigates these challenges better than most, making its cleaning process about as easy as one could hope. But there are certain situations where one of the devices will be more suitable than the other. For example, if you regularly cook for a large number of people, then you might need the 10 qt sized pressure cooker, which is only available in the Duo Nova line. In fact, other machines place their buttons on the main control panel, even farther away from the assault of steam that accompanies depressurizing a pressure cooker. However, the DUO Nova is undoubtedly still in the minority, offering a pressure release button. The steam function uses pressure cooking to steam and again, we struggled to find a good recommendation for timings and plumped for four minutes with one cup of water in the bottom of the pot. The steam rack provided isn’t great for this purpose and some of the broccoli pieces fell through the gaps. Both the Instant Pot Duo and the Duo Nova are available in 3, 6, and 8 liquid quartz. Being able to choose from three different sizes is great and means you can get something that fits in your kitchen perfectly. This range of sizes isn’t typically offered by other pressure cooker brands. We've always Instant Pot models because the lid can be stored upright in either of the handles on either side of the machine. This allows you to put the lid out of the way, no matter which hand you like to stir with, without setting it down on a potentially dirty countertop. For a speedy Thai red curry, the manual pressure cook function was our choice.
