Peruvian Causa with Crab & Avocado (Causa de Cangrejo)
The success of a Causa depends on the starch profile of the yellow potato. Unlike russets, yellow potatoes have a medium starch content that creates a creamy, malleable dough when emulsified with oil and lime. This dish is essentially a cold potato salad constructed with architectural precision, balancing the richness of crab and avocado with the sharp, fruity heat of Aji Amarillo.

Instructions
1
✓
Boil potatoes starting in cold water. Peel and pass through a ricer while still steaming hot.
Tip: Mashing cold potatoes ruptures starch granules improperly, resulting in a gluey, gummy texture. They must be processed hot to remain fluffy.
2
✓
Emulsify the warm potato mash with lime, oil, chili paste, and seasonings. Knead until cool.
Tip: The kneading process incorporates the oil, turning the mash into a smooth dough that won't crack when shaped.
3
✓
Bind the crab meat with mayonnaise and lime.
Tip: The crab mixture should be seasoned aggressively, as the cold potato layers will mute the overall salinity of the dish.
4
✓
Layer in a ring mold: potato, avocado, crab, potato.
Tip: Acidulating the avocado (brushing with lime) creates a barrier against oxygen, preventing unsightly browning inside the tower.
5
✓
Refrigerate for 1 hour to set the structure. Unmold.
Tip: Chilling allows the starches to undergo retrogradation (firming up), which is essential for the tower to hold its shape when the ring is removed.
