Shrimp and butter have always been the ultimate combo, but the additions of bitter, hoppy beer paired with a spicy homemade harissa pack this simple dish with flavor. The shrimp are cooked shell-on under a broiler, yielding plump and juicy flesh. The resulting butter and beer sauce is begging to be mopped up with crusty bread. You won't even need a plate for this one, just dig right into the piping hot skillet.
