Romesco is a tomato-based sauce that originated from Tarragona, Catalonia. The fishermen made the sauce to be eaten with fish. It is like a pesto - typically made from any mixture of roasted tomatoes and garlic, toasted almonds, pine nuts, and/or hazelnuts, olive or sunflower oil, and nyora peppers.
