Questions tagged [food-science]

All about the scientific theories behind food. Cooking myths debunked here.

Questions in this tag usually begin with "why", although the tag may also apply to more experimental science.

If you're looking for a scientific explanation of why a particular technique works (or doesn't work), or why some food looks or tastes the way it does, or if some common bit of cooking wisdom has ever been proven or disproven experimentally, then this tag is for you.

If you just want to know why your recipe didn't turn out right, please don't use this tag.

Note that we also have a tag which should be used for applied science questions, especially those on the subject of food additives such as buffers and hydrocolloids.

Cooking away alcohol

When you cook with wine or spirits, when does the alcohol cook away? Obviously high temperatures will do it, but how low of temperatures will work? Also, does it vary by the type of alcohol?

What does "natural" actually mean?

More and more I see "natural" or "all natural" labels on the slightly-cheaper alternatives next to "organic" products, and I find it somewhat confusing. I know that (for example) tofu does not occur in nature, so obviously "natural" does not refer…

I had a whole bag of Cocoa Puffs that had gone stale, and thought it would be fun to mess around and see if I could bake something with them. So I aimed for muffins. I more or less based it on a banana muffin recipe I make all the time: 2 1/2 cups…
