Ceviche is a seriously however-you-like-it-best dish. I have been eating it in restaurants for about 15 years and they are never the same. Two friends have given me their family recipes and they are dramatically different. The thing that is consistent is that fish is cooked with acid for about an hour and other stuff is added to it. I have had some that was only sauced with the lime juice, some has had avocado blended into the lime to make it creamier and one friend adds mayo to it. This is what I have created for myself and I think these proportions are a decent starting place to tweak it how you like it best. Leave out what you don’t care for. Add more of what you love most. I used my kitchen scale to check amounts as I put it together.
8 oz tilapia in bite sized chunks
6 oz. lime juice to cover the fish
some onion. 1/3-1/2 c?
Mix together and refrigerate for 1 hour or more. Give it a stir a couple of times to be sure all the fish is limed. It’s ready when the fish is all opaque.
While that “cooks,” boil 6 oz shrimp for a couple of minutes until cooked through.
Cut up shrimp in bite sized pieces.
Add some cilantro leaves
6 oz. tomato
1 avocado, chunked or mashed.
half a seeded jalapeno, minced, I’ll probably use the whole thing next time.
little bit of bell pepper, slivered
S&P to taste
Drain the lime juice and stir it all together. I tried it with and without about a tablespoon of mayo and like it both ways.
