Oh! My first reaction was yes, unless you keep strictly kosher. ;) I think it'llcomd down to your particular usage. You can buy extra pieces to make it easier, like changeable seals in different colors, separate liner pots, in stainless, ceramic or non-stick. Nonstick can pick up odors that are hard to wash off. There are different kinds of ceramic pot linings. They shouldn't pick up odors, but I don't know, Do check prices, though. The Instant Pot itself isn't expensive, and the real money is made off those accessories. If you have room, two separate ones might be less money and hassle.

There are a zillion recipes for just about everything, specifically for the Instantpot brand. If you know how to choose good recipes (or ask someone who does), because not all posted recipes work for everyone, you should be able to do anything you want. My own multicooker is Breville, but same principles. It was a gift, and took me a year to figure out what to do with it. Mine is by far the best slow cooker for meat I've used outside of my big fancy wall oven, It's the only pressure cooker I've used. On the stove pressure cookers are supposed tobe better, but if you just need to get an ingredient cooked fast, a multicooker on pressure works just fine. My seal and non-stick liner pot both that on odors and cling to them. I don't use it enough for it to be a bother, and they do air out, but it's an annoyance, and I do think those odors can migrate to the food, though I admit it can be a matter of the senses fulfilling expectation.

I love my multicooker. The thing I make in it most often (given a lot of ways of cooking stuff here) is a hunk of chuck for enchiladas or similar. Dump it in on slow with some vegetables before bed. Done in the morning. Everyone I know who has an Instant Pot brand loves it, too.

'Sure unless you are kosher' was my initial thought too!

The seal is what picks up stains and odors. I have 2 pots. The original cheap off brand ”trial” 6, and genuine Instapot 4 . The 6 is almost exclusively savory cooking. The 4 is neutral grains and sweets. I have multiple seals and pans for both. And they both get used multiple times a week. I might even get an 8. Making yogurt was a big pain though. I’d rather buy it.

Tonight was French onion pot roast, with the 5 lbs of onions sauted and caramelized in the 6, then the previously seared chuck added and left all day. The 4 made the rice when it was time to eat. Add a marinated tomato and cucumber salad.

The Instapot makes the most perfect brown rice. I toss in other ingredients and make it a meal. Frozen veggies, diced tomatoes, black or white beans. I can make a pot and eat it for days.

Recipe

I don't have an issue between protein and making yogurt, I simply put my InstaPot liner in the dishwasher.

Yes, you can do that, just have a separate silicone ring/gasket, like others have already said. i have a separate one for making cheesecake and creme brulee. Bought it on Amazon.

I found that making a curry in the Instantpot the silicone will keep the odors even after dishwashing.

In fact, when using our silicone utensils for a curry cook, they will also keep the odors.

Something that does work for removing odors from silicone parts, although too much of a bother, is to heat the different parts in the oven (the temps escape me right now, but is easily found) on the net.

You don’t use the pressure cooker function to make yogurt. I bought an InstantPot glass lid to use when I’m making yogurt. It works great! So no silicone ring necessary. (I do have 2 silicone rings that I use when making other things in my InstantPot. One of the rings is used whenever I’m making dishes that contain onions, garlic, etc. It has definitely retained those odors.)
