A chaffle combines eggs with what dairy ingredient?

A chaffle combines eggs with cheese.

The word chaffle is a blend of “cheese” and “waffle.” It describes a low-carbohydrate waffle-like food made primarily by cooking eggs and cheese in a waffle iron. The cheese supplies much of the structure and savory flavor, while the eggs bind the mixture and help it set as it cooks.

Chaffles became popular in low-carb and ketogenic-diet communities as an alternative to bread, buns, or conventional flour-based waffles. Recipes vary: some use shredded mozzarella for a mild, stretchy result, while others use cheddar or another firm cheese for a stronger flavor. Almond flour, herbs, spices, or pork-rind crumbs may also be added, but they are optional rather than the defining ingredients.

A chaffle is not simply a standard waffle topped with cheese. Cheese is part of the batter itself, which is why it can brown and crisp directly against the waffle iron. Butter, cream, and yogurt may appear in other waffle recipes, but they do not supply the defining pairing expressed by the name.
