How is Ceviche "Cooked?"

What does it mean to have cooked something? Most people are probably thinking cooking involves a heat source to break down proteins. But what about ceviche? No heat source is used to “cook” ceviche but it still undergoes a process where proteins are denatured. We’re taking a closer look at proteins why they denature.

Serious debate time: which amino acid is the best amino acid, and why is it absolutely not glycine?

The consistently high-quality editing of these videos is impressive. I understand that some instructors incorporate videos into their teaching, and this approach would definitely inspire me to engage more deeply with the subject of chemistry. It's worth noting that food is one of the most universally shared aspects of our lives.

Cured egg yolks are great. They have an umami, slightly salty taste and can be grated and used similarly to parmesan cheese.

Jikes, so only sushi grade fish is recommended? That's rough, in Mexico we also make a lot of ceviche and with almost any kind of fish 😅 🐠🐟

@rianfelis3156 8 ай бұрын

Sushi is also traditionally made with any kind of fish. After all, flash freezing was only invented in 1924. You make sure that it's fresh enough to avoid excessive bacterial growth, and just live with the parasites. Not that long ago, people just lived with a lot more parasites, which had all kinds of effects, and traditional medical texts were full of ways to get rid of some of them. Effectiveness of those cures wasn't really guaranteed though.

Tangential fact, but if memory serves, you can uncook an egg with vitamin C. One of Herve Thiss experiments I believe. (One of the fathers of molecular gastronomy.) Makes me wonder if you could uncook other things, but Id imagine it almost always gets far too complicated.

Not all proteins are digested equally. For example, cooking makes egg proteins up to 180% more digestible. Cooking also denatures plant lectins, commonly found in beans and grains, that would otherwise cause severe food poisoning. Eating just four raw red kidney beans can cause illness

This is how to make egg in alcohol more palatable: Add milk, cream, sugar, and maybe some nutmeg. Eggnog, anyone? As for salt cured egg, I wonder if this is how salted duck eggs are made -- no heat applied?? Then by extension, century eggs are also "cooked" without heat? Whoa, I had no idea!

You forgot to mention that cooking meats helps human digestion because we are omnivores, not carnivores. That is why fire was so essential for early humans. I'll stick with heat. I can't eat acid because of severe reflux and i shouldn't eat salt because of high blood pressure, as for alcohol, i try to avoid it because of the possible interactions with my meds.
