To choose the perfect artichokes for the Instant Pot, make sure they are a mild green color all over. A few brown spots are normal, but you do not want your artichokes to have purple spots or big bruises. In addition, you want to avoid artichokes with any flowers or buds appearing. Instead, choose those that have tightly packed leaves that firmly snap when bent. The artichoke should also feel firm and bulky, not hollow. When you give the artichoke a slight squeeze it should squeak. If the artichoke has a long stem as well, you’ve hit the jackpot!
