Fra Diavolo means “Brother Devil". In Italy, this refers to a dish that’s sprinkled heavily with black pepper and grilled. But in America the term is associated with spicy hot-pepper sauces, like the lobster Fra Diavolo that became popular in the 1930s and has been a fixture on Italian-American menus ever since. (It is actually unknown in Italy, where they don’t have the same type of lobsters we do.) I make my version of Fra Diavolo with shrimp because it’s lighter and easier for everyday cooking.
