Has anyone ever cooked fresh clams? My mom bought some so I'm cooking them tonight and I started with one recipe that said if they dont open toss them out. Then I switched to a different recipe that said if they don't close when you tap them toss them. I read that after they were already steaming. I'm a little nervous about eating them and getting food poisoning or something because I didnt tap them first. They all did open though. Any tips?
