The tapas dictionary

Croquette
A croquette is a fried fritter, typically made with a béchamel sauce and finely chopped ingredients such as ham, chicken, or cod. It is usually served as a tapa or appetizer, often with a drink. Its origins trace back to France, but it has become extremely popular in Spain.
Rabo de Toro
Cascoporro is not an ingredient. It is a colloquial Spanish word that nearly always appears in the phrase «a cascoporro», used above all in Castilla-La Mancha and other rural areas. It means in large amounts, in abundance, loads of it. Applied to a tapa, it means an ingredient is served generously.
