The is what I found out for the preparation of "angry" for a lobster.
In this lobster recipe, pieces of lobster are roasted in a very hot oven with white wine, herbs and crushed red pepper to make a spicy sauce. The angry in the name most likely comes from the hot pepper, but some say cutting up the lobsters sets the tone for this dish. Serve with crusty bread to sop up the sauce and plenty of fresh napkins.
