What is origin of souffle?

Soufflé comes from the French word "souffler", which means "to blow" or "to puff up". The word was first used to describe a light and fluffy dessert made with egg whites and sugar, which was popular in France in the 18th century. Over time, the term came to be used more broadly to describe any dish that is made with a mixture of egg whites and another ingredient, such as cheese or vegetables, that is whipped until light and fluffy and then baked or steamed.
