Why it works: Gruyere cheese and butter work together. They rank in the top 9% of all ingredient pairs, and cooks put them together in 323 recipes. Both carry gamma-decalactone, which smells peach, creamy. The science ↓
Fondue
Ingredients
Directions
Prepare
Weigh the eggs based on the number of guests.
Weigh out Gruyère cheese to be 1/3 of the egg weight and butter to be 1/6 of the egg weight.
Break and beat the eggs in a basin, then add the butter, grated cheese, salt, and pepper.
Cook and serve
Heat a saucepan over a clear flame with a small piece of butter the size of a nut until melted.
Pour the egg mixture into the saucepan and stir with a spoon until thick but very soft.
Serve warm on a dish and bring it quickly to the table.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the structure that sets into a thick, soft, custard-like body.
- Gruyere cheese
- Adds rich flavour and melts into the eggs for a creamy, smooth texture.
- Butter
- Adds fat for a silkier mouthfeel and helps keep the mixture from sticking.
The step that matters
Stirring the egg mixture over heat. Eggs set when heated, so stirring gently over a clear, moderate flame keeps the mixture thick but very soft. Too much heat or too little stirring can make it curdle or turn grainy.
