Lima's cold tower: layers of yellow potato mashed with ají amarillo paste and lime juice, alternating with a filling of tuna or chicken mayonnaise. Set in a cylindrical mould and unmoulded to reveal a terrine. The ají amarillo potato layer has a gentle fruity heat — not sharp, not burning, but warm — that is specific to this chilli variety.
“Lima's cold tower: layers of yellow potato mashed with ají amarillo paste and lime juice, alternating with a filling of tuna or chicken mayonnaise.”
The ají amarillo paste turns the mashed potato a vivid yellow-orange. This is not food colouring — it is the natural colour of the chilli.
What to Expect
The causa arrives unmoulded on a plate, the yellow potato layers visible in cross-section. You cut vertically through the layers — potato, filling, potato — and eat with both textures together. The ají amarillo heat is gentle.
Why Try It
Causa tells you about Peruvian cooking's relationship with its Andean potato heritage — a country with 3,000 potato varieties that uses them as a canvas for colour and flavour.
Insider Tips
