I was explaining this to my daughter in quite simplified terms the other day- we evolved to taste sugar and enjoy it because finding a sweet edible plant meant we had a source of energy to help us hunt that day. Pretty useful if you’re a hunter-gatherer.
So we seek out sugar. Now we can get it whenever we want it, in much more massive quantities than we are supposed to be processing. Most of us are addicted. I’m not an exception.
The actual acid (acetic in vinegar, citric in citrus and tomatoes) actually boils off with the water. So a long simmer actually removes the acid and changes the pH of the dish.
Oh shit, that’s super interesting! Really appreciate you sharing that, now I wanna go read more about that some time!
