Lima's cold potato tower, yellow from ají amarillo, layered with tuna or chicken, is served at every Lima lunch table and has been for 200 years.
About Causa Limeña
Lima's cold tower of flavour, layers of yellow potato mashed with ají amarillo paste and lime juice, alternating with a filling of tuna or chicken mayonnaise or crab; set in a cylinder mould and unmoulded to reveal a terrine-like presentation; the ají amarillo potato layer has a gentle fruity heat unique to Peru's most important chilli; a Lima restaurant staple for 200 years.
The Tower
Causa limena is Lima's cold potato terrine: layers of yellow potato mashed with aji amarillo and lime, alternating with a filling of tuna or chicken in mayonnaise, pressed in a mould and unmoulded into neat layers. Served cold, it is a starter rather than a main. The bright yellow potato and the creamy filling are its two essential parts.
“The bright yellow potato and the creamy filling are its two essential parts.”
The Yellow Potato
The vivid colour of the potato layer comes from aji amarillo paste, not from any dye. The chilli tints the mashed potato a deep yellow-orange and lends a gentle, fruity heat that is warm rather than sharp. Lime juice brightens it and keeps the potato from being heavy.
The Andean Potato
Causa is rooted in Peru's extraordinary potato heritage, a country with thousands of native varieties. The dish treats the potato as a canvas for colour and flavour, layering and moulding it like a terrine. It is a reminder that the potato is Peruvian in origin, central to the country's cooking.
How It Is Served
Causa is unmoulded onto the plate so the layers, potato, filling, potato, show in cross-section, sometimes garnished with olive, egg and avocado. It is eaten cold as a first course, the gentle chilli heat balanced by the cool, creamy filling. Bright, colourful and refreshing, it is a fixture of the Lima lunch table.
What to Expect
The causa arrives unmoulded on a plate, the yellow potato layers visible in cross-section. A vertical cut through the layers, which consist of potato, filling, and potato, allows the diner to experience both textures together. The ají amarillo heat is gentle.
Why Try It
Causa reveals Peruvian cooking's connection to its Andean potato heritage, a country with 3,000 potato varieties that uses them as a canvas for colour and flavour.
Insider Tips
