The main ingredient in traditional pasta is flour, usually semolina flour made from durum wheat. This flour contributes to pasta's firm texture and ability to hold its shape during cooking. Water is the other essential ingredient, which is mixed with the flour to create a dough that is then kneaded, rolled, and shaped into various forms—such as spaghetti, fettuccine, or lasagna. While some variations of pasta may include additional ingredients like eggs, the foundational concept remains the same: simple, high-quality ingredients yielding a versatile and delicious staple food in many cuisines worldwide.
