A buñuelo (Spanish: [buˈɲwelo]) (alternatively called bimuelo, birmuelo, bermuelo, burmuelo, or bonuelo; Catalan: bunyol) is a fried dough ball. It is a popular snack in Argentina, Bolivia, Colombia, Cuba, Guatemala, Mexico, Peru, Puerto Rico, Spain, Turkey, Greece, and Morocco, and is a tradition at Christmas, Ramadan, and among Sephardic Jews at Hanukkah. It will usually have a filling or a topping. It is also an "essential dish" in Mexican cuisine.
Buñuelos are first known to have been consumed among Spain's Morisco population. They typically consist of a simple, wheat-based yeast dough, often flavoured with anise, that is thinly rolled, cut or shaped into individual pieces, then fried and finished off with a sweet topping. Buñuelos may be filled with a variety of things, sweet or savoury. They can be round in ball shapes or disc shaped.
