Keep it simple. Remember your eating shrimp or scallops. Don't load them down with a lots of seasonings when cooking them this way. You will enjoy tasting the real wonderful taste of your seafood the way its is. And is suppose to be. Try it . You will fix these jewels of the sea often.
Clean the shrimp and then butterfly style, tails off. Put Scallops or Shrimp or both in ice water. Soak them so flour will lightly stick on them.( No eggs. )
Turn heat up to Med. and place Shrimp or scallops in one at the time leave enough space so you can slowly turn them from under so the crust will stay on them. 2 minutes on 1 st flip. after flipping them put lid on them and turn heat off let sit for 3 minutes, remove them so crust will stay on them with flat turner and serve hot.
