Ceviche is very popular food in America. There are many ways to prepare it and there are many recipes per countries. The Guatemalan ceviche is based on roma/plum tomatoes, onions, garlic, mint, cilantro, soy sauce, English sauce, lemon juice, hot peppers (chiltepe), seafood (shrimp and Guatemalan clamshell especially) and is usually served with cold beer (Gallo Beer).
I leave you with a slideshow of the different kinds of ceviche found in Flickr.
I am posting this photo for a friend who is in Paris at the moment.
