Does the acid in ceviche cook the fish?

The acid in the citrus denatures the proteins in the fish, causing it to become opaque and producing a firm texture. A more common way of denaturing proteins is by exposing them to heat (essentially, cooking them). So with ceviche, the fish is effectively “cooked” even though there’s no heat involved.

How does acid cook ceviche?

At its most basic, it consists of slices or chunks of raw fish (or sometimes shellfish) tossed with an acidic marinade, most commonly plain citrus juice. As the pieces of fish sit in the marinade, the citric acid from the juice slowly causes the flesh’s proteins to denature, in very much the same way that heating will.

What is the chemical reaction in ceviche?

Though it is never “cooked” in the traditional sense, ceviche goes through a chemical process that effectively rearranges the fish’s proteins, much like the application of heat. Both heat and citric acid are agents of a chemical process called denaturation.

How does lime cook ceviche?

At its core, ceviche is basically fresh seafood steeped in an acidic marinade, most commonly lime or lemon juice. The acid in the citrus forms an extremely low pH condition to denature the fish protein networks, much the same as heating would. This results in the seafood becoming opaque and more firm in texture.

What does citric acid do in cooking?

Citric acid can be used to replace liquid lemon juice or vinegar in recipes to add a sourness. It can enhance the flavor in a citrus-based recipe.

How does lime juice cook fish?

The acid in the lemon juice chemically denatures the proteins in your fish, similar to the way that the proteins are denatured when heated.

Can you cook ceviche with acids?

This can be done by heat, but acids can do this as well! Acids will interact with the side chains of the proteins causing similar changes. Commonly used acids are lime & lemon juice. Since the acid will not cause the evaporation of any moisture, the fish won’t be as prone to drying out. That said, it is possible to ‘overcook’ ceviche!
