The Great Chemistry of Ceviche

what is Ceviche and from where does it comes from?

Don’t be scared because of the Word chemistry, there will be no quizzes here, I promise, but there is an undeniable thing that happens with ceviche, a great dish made with fish or shellfish marinated in citric acids, it is a very common dish in many Latin American countries, mostly on the west coast of the continent with the Pacific Ocean and its biological diversity and it is also part of the cultural patrimony of Peru.

Now, why chemistry you may ask, well, unlike sushi the fish or shellfish of the ceviche is not raw, and you might think that that is crazy but cooking is not only about frying or baking something, it is transforming something and making it an amazing edible experience, strictly talking there is no heat application here whatsoever so we cannot really talk about cooking, so if you are wondering how is the fish “cooked” it is mainly because of the acids that are involved.
The usual way to add the acids is with lemon or lime juice on the fish or shellfish and to let it marinate for a while, what happens here is magical, the acids just like the heat, start coagulating the proteins of the meat, and come on, isn’t fish and lime the best combination of the sea? So even that there is no “cooking” involved the acids have a similar effect to the meat than the heat.

The most common ingredients of ceviche include hake, tilapia and Marlin fish, shrimps and a variety of mussels and clams with the essential lemon or lime juice, and spices like salt, black pepper, garlic, onion and cilantro and even jalapeño for that extra spicy flavor, of course, the ingredients may vary depending on the location, so people may add avocados vinegar or even ginger ale instead of the fruits.

So if you want to impress a special someone with a different dinner experience or with a nice beach meal or just to make with some friends here we have some recipes for you, it is advised that days prior to making ceviche that you freeze the fish at a temperature of -20ºC for 7 days or -36ºC for 24 hours to reduce the chance of any possible sign of bacteria or parasite.
