Shrimp Fra Diavolo is an Italian-American creation of shrimp tossed into a spicy sauce made from little more than tomatoes, garlic and red pepper flakes. This recipe throws in mussels too, because it seems like a crime to make a seafood dish without them. Namely, because mussels are delicious, but also because tucked into each blue-gray shell is a healthy serving of protein, B-vitamins, selenium, zinc, magnesium and manganese.
You could make this dish entirely with mussels and turn it into Mussels Fra Diavolo, if only shrimp didn’t play such a key role in transforming the tomatoes into a rich and flavorful sauce instead of just bland marinara. The trick? Browning shrimp shells then simmering them in broth creates a quick but really flavorful seafood stock. The stock can then be used as a base for any soup, bisque, chowder or sauce you make.
