Causa is a mashed yellow potato dumpling mixed with key lime, onion, chili and oil. Varieties can have avocado, chicken, tuna (typically canned) or even shellfish added to the mixture, usually served cold with hard boiled eggs and olives. Here, the crab causa is made with the yellow potato mash and layered with fresh crab.
