The Spanish ring-shaped fried pastry traditionally made in several regional styles is called a rosquilla.
Rosquillas are small ring pastries whose dough, flavoring, and finish vary by region. Recipes may include eggs, flour, sugar, anise, lemon, or olive oil, and the pastries can be fried or baked depending on the particular style.
Different varieties have distinct names and textures. Some are plain or crisp, while others are glazed, coated in sugar, or made softer with a richer dough. Rosquillas are especially associated with Spanish festivals and local celebrations.
They are sometimes translated simply as “Spanish doughnuts,” but that label hides their regional diversity. They should not be confused with churros, which are usually ridged sticks or loops made from choux-like dough.
