Spaghetti with watercress and anchovy sauce is a delicious and flavorful pasta dish. The sauce is made by saut茅ing garlic and anchovies in olive oil until the anchovies melt into a rich and savory paste. Watercress is then added and cooked until wilted, adding a fresh and peppery flavor to the sauce. The cooked spaghetti is tossed in the sauce, allowing the flavors to coat each strand of pasta. This dish is a perfect combination of salty, savory, and slightly bitter flavors, making it a satisfying and unique pasta option.
