Red clam sauce is a flavorful Italian sauce made primarily from clams, tomatoes, garlic, and herbs. It is often served over pasta, making it a popular dish in Italian-American cuisine. The sauce can vary in thickness and flavor, depending on the recipe and the type of clams used. Typically, the clams are cooked with sautéed garlic and onions, then combined with crushed tomatoes and seasonings like oregano and red pepper flakes. This combination creates a rich, savory sauce that complements the briny taste of the clams, making it a delicious option for seafood lovers.
