Why do people cook fish with lemon?
Digestive Aid. The acid in lemons is capable of breaking down the proteins in seafood the same way cooking does. Some fish recipes call for extended acidic marination to cook the item in place of heat.
Does citric acid cook raw fish?
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. The result is raw fish with the opaque appearance and firmed texture of cooked fish.
Does citrus actually cook fish?
Technically speaking, cooking requires heat, so ceviche (also known as seviche or cebiche), a dish in which raw fish is marinated in citrus juice, isn't cooked. But it's not exactly raw, either. Both heat and citric acid are agents of a chemical process called denaturation.

Can you get sick from ceviche?
Ceviche is raw seafood marinated in lime or lemon juice. Like sushi, there's a chance it can have bacteria and parasites that can cause food poisoning.
Step 1
Remove the skin, bones and blood line from your fish once you have defrosted it. While you can use any fish to create ceviche, saltwater white fish like sea bass, mahi mahi, flounder and grouper work best. These types of fish have a semi-firm texture and light flavor, which will "cook" well with the lemon juice.
Step 2
Chop your fish into small cubes, around an inch in size, and place them in a glass bowl. Lemon juice will denature small pieces of the fish more evenly than larger ones, and impart some tangy flavor to them.
Step 3
Squeeze several lemons to make enough juice to cover your fish. Fresh juice gives the fish the nicest flavor but you can also use bottled juice, which is slightly more acidic and may cook your fish a little faster.
Step 4
Dice a few onions to add to the fish. The onion will become softer when marinated in the lemon juice, and will impart a pleasant flavor into the fish.
Step 5
Cover the fish in lemon juice and sprinkle some salt on the fish for flavor.
Step 6
Marinate the fish in the lemon juice for at least 30 minutes and up to 6 hours, in a covered bowl. Place the bowl in the refrigerator at 40 degrees F, or lower.
Step 7
Check the fish after 30 minutes to an hour to see if it's ready, as some types of fish may denature more quickly than others, and can become mushy if marinated too long. The flesh of the fish should be white, firm and opaque.
Step 1
Cut the tuna into slices or cubes and place it in a nonreactive bowl. Nonreactive materials include stainless steel, plastic and glass.
Step 2
Pour lemon juice over the tuna in the bowl and stir to coat it using a plastic, wooden or stainless-steel spoon. A basic ceviche comprises eight parts seafood to one part acid.
Step 3
Add a few simple, fresh flavoring ingredients to the ceviche. Just about any ingredient goes well with lemon-marinated tuna, but ceviche is best prepared using only three or four of the freshest ingredients. Classic preparations call for chilies, sliced onions and roughly chopped cilantro.
Step 4
Add a drizzle of oil to the ceviche, if desired. Since you're not cooking the tuna with heat, use a high-quality, flavored oil, such as avocado oil or extra-virgin olive oil.
Step 5
Season the ceviche to taste with kosher salt and freshly ground black pepper. In addition to seasoning, salt plays a role in "cooking" the ceviche.
Step 6
Stir the ceviche and cover the bowl with plastic food wrap. Place the bowl in the fridge.
Step 7
Let the tuna "cook" for one hour per half pound. Stir the ceviche every 30 minutes. If you want to add diced avocado, stir it in right before you serve the ceviche.
Liver Flukes
Liver flukes are a family of parasitic flatworms that cause a disease known as opisthorchiasis.
Tapeworms
Fish tapeworms are transmitted to people who eat raw or undercooked freshwater fish or sea fish that spawn in freshwater rivers. This includes salmon.
Roundworms
Parasitic roundworms may cause a disease called anisakiasis. These worms live in marine fish, or fish that spend a part of their lives in the sea, such as salmon.
What happens when cooking fish
Before we can dive into ceviche science we have to start at the basics. What happens when cooking fish? We’ll start with the more common method of cooking fish: simply using heat.
What is ceviche?
Ceviche is fish that has not been heated, instead, it is cooked by immersing it in an acid. As we discussed above, one of the most important steps of cooking fish is the denaturation of proteins. 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.
Safety of ceviche
Since fish isn’t heated during the acid treatment, micro organisms aren’t killed by heat as usually is the case. The acidic environment might slow down the growth of some micro organisms, however, it does not necessarily kill the micro organisms (most will simply stop growing or slow down, but won’t necessarily be killed in this short time span).
Ceviche recipe
Below is a suggestion for a ceviche recipe, recipe can be varied a lot and the exact cooking time will depend on the limes and lemons you’ve used and their acidity. The more you dilute the lime & lemon juice, the less sour it becomes and the longer the cooking process will take. A few last ceviche science guidelines:
Instructions
Cut the fish in evenly sized pieces (if the size difference is very large some will cook a lot faster than others).
Sources
Serious eats seems to have tested just about everything in food and cooking, including this ceviche.
Community Q&A
Does lemon juice mixed in egg yolks cut out danger of illness with uncooked eggs?
Tips
If a recipe or technique only requires a few drops of lemon juice, poke a toothpick through the skin and slowly squeeze out whatever amount is needed. Plug the hole back up by sticking the toothpick back in and store the lemon in a sealable plastic bag inside the refrigerator.
Warnings
Marinate meats, poultry, and fish in a non-reactive dish. Glass and plastic work best, but stainless steel can also be used. Do not use aluminum, however, since aluminum will react with the acid and leave your food with a metallic taste.
