I had an electric quite some time ago, and I used it alot. I got one for xmas last year and I finally cracked it open last month. If you are a meat eater, then stewy things are a good bet. I made a chuck beef stew with mine for the first trial and it would up being just fine. I tried to follow the recipe tips that came with the booklet, and it was just fine. Some suggestions:
You probably have a searing or browning setting. Nice, in theory, but depending on the size of the vessel, it might be annoying to have to brown 4 batches of meat. I can brown bigger batches stovetop, and generally do.
Figure out what the pressure cook times of whatever you are cooking are, or at least, give it serious consideration. If you add carrots, meat, potatoes and say, celery, all at once, the carrot and celery will be paste by the time the meat is tender. You can release the pressure and add ingredients as you go, depending on how long the ingredients need to cook.
Try to allow enough time to let any stewy thing you make cool completely before reheating and serving. I don't know the science, but I'm assuming it has something with letting the juices soak back into the meat. In my exp, with the pressure cooker, meats are far more tender after they cool off. (And also, same as any other stewy cuts, much better the next day.)
As a meat-eater, I'd suggest:
Short ribs
Beef stew
Nihari
Vindaloo with stewy cuts of lamb, pork, or chicken thighs.
Rogan josh, same deal.
Dals, and other pulses.
Shanks
I'd bet a big ol pot of neckbones would be good, but I've never done it.
Funny, I bought a big ol honkin chuck yesterday, and I am gonna pull the pressure cooker out today for it.
Once you figure out your cooktimes, it really is a time saver. A method for beef stew:
prep your meat (cube if needed, while geting pan hot for browning)
Brown it stovetop, set aside
While meat is browning, dice an onion, and however much garlic you think will be nice. After the meat is done, lower the heat, and add the onion. When almost translucent, add garlic and bay leaf - and any other spices you might like for your stew. I'll add flour at this point if I remember, but I generally always forget. Let the spices bloom, and deglaze with the liquid you plan to use. Transfer it all to the cooker, and go. Start prepping the veggies you want. When it makes sense, add the potato. When it makes sense, add the carrot, when it makes sense, add bigger pieces of onion, etc, etc. When it's all done is when I realize I forgot the flour, then whip up a very light cornstarch slurry and toss it in. Let it cool and reheat and eat. It's seriously like an hour for me, start to finish - minus cooling/reheat time. About enough time after picking up from pre-school, and giving jr a half hour drawing project, and an episode of Doc Mcstuffins, while I listen to Pandora's "Urban Comedy" for a quick chuckle after work while cooking.
