Causa limeña — a layered terrine of seasoned mashed yellow potato (with ají amarillo and lime), filled with avocado, chicken or tuna salad, and finished with a drizzle of huancaína sauce — is Lima's signature cold dish. Peru has over 3,000 varieties of potato (the potato was domesticated in Peru 8,000 years ago), and causa showcases the papa amarilla (yellow potato) — waxy, golden, and naturally buttery — at its finest. The dish is architectural: layers of vivid yellow potato alternating with green avocado and white protein, pressed into a mould and unmoulded at the table.
- **Papa amarilla is the potato.** Yellow, waxy, naturally creamy. No other potato produces the same colour, texture, or flavour. When mashed with ají amarillo and lime juice, it becomes a vivid gold that needs no other colour. - **Cold, never hot.** Causa is served cold or at room temperature. It is not a warm dish. The cold temperature firms the potato and allows the layers to hold their shape when sliced. - **The lime juice is structural, not just flavouring.** The acid sets the potato starch slightly, helping the causa hold together when unmoulded. Without sufficient lime, the layers collapse.
