I recently got an Instant Pot and while there are a plethora of recipes for it online, I decided to see what could be found in a more formal cookbook. Like most cookbooks, results are mixed, but I did find some really interesting ideas.

Pressure Cooker Perfection by America's Test Kitchen
America's Test Kitchen always has solid recipes so it's not surprise that this
is a good collection, but it is clearly geared more toward traditional pressure
cookers than electric ones. There are adjustments included for electric
pressure cookers, however, so you can still use the recipes included. I
got some interesting ideas & will try a few of the recipes.

Instant Pot Miracle by the editors at Houghton Mifflin Harcourt
A
nice collection of IP recipes, and one of the better books I tried. I found several recipes that I’m looking forward
to trying. Most recipes call for fresh ingredients rather than canned goods or pre-made ingredients, which appeals to me and the book includes meals for all times of day
as well as sauces & side dishes. There's a lot in here to like and the recipes are easy to understand.

The Ultimate Instant Pot Pressure Cooker Cookbook by Ella Sanders
This cookbook had some of
the most unique recipes I've found for the instant pot, but I didn't find many that I actually want to make
(though there are certainly a few). Still, if you're looking for ideas
that you haven't seen on every other blog or book, The Ultimate Instant
Pot Pressure Cooker Cookbook is not only a mouthful to say, but looks
like a good investment.
BUT, I found that some of the recipes
were not written clearly. Sanders uses the Instant Pot's Manual mode in
most recipes, which is fine, but she doesn't specify whether to use high
or low pressure (I assume high, but what if I'm wrong?). There are also
instances where I think she's talking about using the Saute mode, but
she doesn't specify & in fact a few times it sounded like she wanted
the pot set up for pressure cooking, but to leave the lid off. Perhaps
this was written for a specific version of the IP? I don't know because
she isn't specific, but reader beware that there will be some reading
between the lines & interpretation on these recipes.
