Linguini is a long, thin type of pasta that is made from wheat flour and water. It is similar in appearance to spaghetti, but it is usually flatter and wider. The word “linguini” comes from the Italian word for tongue, which may refer to its long, narrow shape. Linguini is believed to have originated in the Italian region of Liguria, where it is still a popular dish. In addition to being served with traditional tomato-based sauces, linguini can also be used in a variety of other recipes, such as soups, salads, and casseroles.
