Buñuelos are bite-size dough balls popular in South American countries like Venezuela, Argentina, Belize, Bolivia, Colombia, Cuba, Puerto Rico. They are also commonly found in parts of Mexico and Spain.
The sweet dessert is made with slightly different ingredients depending on where it's made — in Mexico, for example, they're often served with a sweet syrup called piloncillo, and in Colombia they are a Christmas treat usually made with cheese.
Buñuelos can be tricky to make, but they are said to bring good luck if they're eaten during the holiday season.
