Since this is such a common question on our site, and there are some very obvious similarities between questions on this topic, I feel like maybe it should have a tag. It's a pretty pedestrian topic but nevertheless, a tag would make it a lot easier to find and sort duplicates and also have some canonical information for "how not to overcook your food".
What do you think? Is there a culinary term for this? At first I thought "overcooking" but the trouble is that a lot of people don't realize that's what they're doing, and have to have it explained to them. We have texture but it seems too generic for this.
Feel free to vote down if you don't think it justifies a tag (i.e. maybe we should just close these all as dupes rather than attempt to categorize them...)
