Why does a covered pot boil over




















Pasta is one of the most likely foods to cause a boilover because of the preferred cooking method that calls for a large amount of water. However, other starchy foods such as rice and dried beans also will boil over if they are cooked in a large amount of water in a small pot. To prevent boilover, Whistler and several of his colleagues suggest these solutions: Add a small amount of butter or oil, which will break up the starch at the top of the water and allowing air to escape; lower the heat once the boil has been reached; and use a larger pot with less water.

Frequent stirring also helps reduce the likelihood of boilover. Q-When my mother made pickles, she only used the flat canning lids once.
