What is a "doughnut" primarily made of?

The primary composition of a "doughnut" is typically fried or baked dough that is sweetened. This foundational characteristic distinguishes doughnuts from other pastries and treats. The dough includes ingredients such as flour, sugar, eggs, and milk, resulting in a sweet and satisfying product.

The process often involves deep-frying, which contributes to the doughnut's unique texture and flavor, or baking, which can offer a lighter version. The sweetening of the dough can include sugar and flavorings, which enhance the final product's taste profile.

While other options present variations or different types of pastries, they do not capture the essence of what defines a traditional doughnut. These variations may have different fillings or textures but do not align with the basic definition of a doughnut as primarily consisting of sweetened dough.
