Ceviche Variations. Ceviche is usually made with sea bass or flounder, but just about any fish or shellfish will work. The other ingredients vary widely. Ecuadorean ceviche is often made with shrimp and ketchup in addition to the lime juice and served with corn nuts. In Chile, ceviche is made with Chilean sea bass, grapefruit juice and cilantro.
If you find the ceviche a little too acidic, drain out some of the juices after the marinating, add a little more avocado (or some olive oil) and/or a little more salt. 1  1 pound medium-small shrimp, peeled and deveined. 2  2 Tbsp salt. 3  3/4 cup lime juice (juice from 4-6 limes)  3/4 cup lemon juice (juice from 2-3 lemons)
