Croquetas, or Spanish croquettes, are a popular snack or appetizer in Spain. These small, cylindrical bites are made by mixing a creamy béchamel sauce with various fillings such as ham, chicken, seafood, or cheese. The mixture is then breaded and deep-fried until crispy on the outside and creamy on the inside. Croquetas can be served as a standalone snack, or as part of a larger tapas spread, and are typically enjoyed with a cold beer or a glass of wine.
