The 100 folds in a chef's toque are said to represent 100 ways to cook an egg.

In the early days, the number of pleats in the chef's hat represented the number of recipes a chef knew for a given food item, like egg or chicken. Having a hat with 100 pleats meant he knew 100 recipes to prepare with an egg. The same applied to the height of the hat. The taller the toque, the more a chef knew.
