astelena:::croqueta de pistacho (pistachio croquette)
Plaza Constitución, 1::Donostia-San Sebastián.
One of my (many) hobbies is seeking out weird croquetas. Croquetas are ubiquitious in Spain and Basque Country. The only mandatory characteristics are a base of bechamel, some sort of coating, and fried yumminess. This example from Astelena is unique, slightly sweet and delicious.
