What's white and you eat it every day?

Miku and I were reading a "colors" book, learning the words for colors and thinking about other examples of things that are such-and-such color. For example, for things that are purple, she came up with "shirt" and "colored pencils." But the best one was for white. We had snow and carpets and shirts and your eyeball and all that stuff but I hinted to her "it's something you eat every day" and she immediately replied with "MARSHMALLOWS!!"
