Omelets are a popular breakfast dish that can be made with a variety of ingredients. The most common omelet ingredients are eggs, yolks, oeufs, and raweggs. Eggs are a staple ingredient in omelets, providing the base for the dish. Yolks are the yellow center of the egg, and they add flavor and texture to the omelet. Oeufs are a French term for eggs, and they are often used in omelets as well. Raweggs are also sometimes used in omelets, although they must be cooked thoroughly before being added to the dish. All of these ingredients can be combined to create a delicious omelet.
