Hi @karen00 - I was a little afraid too since I'd never used a pressure cooker. I practiced a few times with a cup of water just "cooking" for 2 minutes then doing a quick release of the pressure. After my practice I've been fine. Last night I did sweet and sour pork. It was delicious. I used pork tenderloin cut up into 2" strips. I sauteed them just to get a quick brown on the meat. Them I put the meat in the instapot along with a diced onion, a diced green pepper and this mixture: 1/4 cup pineapple juice, 1/4 cup cider vinegar, 3 Tbls low sodium soy sauce, 1 Tbls Worcestersire sauce, 1/2 tsp salt, 2 Tbls brown sugar. I cooked it on high pressure for 10 minutes. Then added pineapple chunks, thickened up the sauce with some cornstarch and water, and served with basmati rice. It was yummy. And I have enough left over for another meal!
