Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Cheese Fondue
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the base
Mix the first 7 ingredients together.
Add the well-beaten egg yolks.
Fold and bake
Cut and fold in the stiffly beaten egg whites.
Pour the mixture into a buttered baking dish.
Bake at 350°F (175°C) for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lift and structure, while yolks enrich and help set the custard.
- Cheese
- Provides fat and flavor, and melts into a smooth, creamy texture.
- Milk
- Forms the liquid base that gives the mixture a soft, moist body.
- Bread crumbs
- Soak up liquid and add body, helping the fondue hold together when baked.
- Butter
- Adds richness and flavor, and greases the dish to prevent sticking.
The step that matters
Fold in the egg whites. Stiffly beaten whites hold the air that makes the fondue rise. Cutting and folding gently keeps that air in; stirring hard deflates the whites and leaves a dense, flat result.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (milk, butter, bread, cheese, pepper, egg):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against milk, butter, bread, cheese, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
