Elena Hernández, the Panama City-based chef and a great admirer of Peruvian cuisine, recently posted her recipe for causa de atún, tuna causa, on her Spanish-language blog, El Amor por la Cocina. This cold potato appetizer, somewhat like a spicy and flavorful layered potato tarte, one of Peru's most typical dishes, is also one of Elena's favorites. For the first time, and adapting from Tony Custer's book, The Art of Peruvian Cooking, Elena tries her hand at causa. Below is her easy-to-follow recipe. Causa de atún, tuna causa.
