Q: What does “cover beans with two inches of water” mean? Is it two inches above the beans? Exactly two inches of water in the pot? Or what?

Editor: Since pots and pans vary in sizes, covering something with two inches of water means there should be two inches of water covering the top of the food, not that there are exactly two inches of water in the pot. This means that there is plenty of water to keep the food completely covered in water as it cooks.

Readers, is this how you interpret this common recipe instruction?
