Why it works: Butter and gruyere cheese 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 and note the total weight.
Measure out butter to equal half the weight of the eggs.
Measure out grated Gruyère cheese to equal a third of the weight of the eggs.
Break and beat the eggs thoroughly in a saucepan.
Cook and serve
Add the butter and cheese to the eggs.
Place the saucepan on the fire and stir with a wooden spoon until thickened like custard.
Add pepper and salt to taste.
Serve immediately without allowing it to boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Coagulate as they heat, setting the mixture into a thick, custard-like body.
- Butter
- Adds richness and a smooth, silky mouthfeel as it melts into the eggs.
- Grated gruyère cheese
- Adds savoury flavour and body, and melts into the eggs to thicken the mixture further.
The step that matters
Stirring over heat without letting it boil. Egg proteins set gently with steady stirring over moderate heat. If the mixture boils or overheats, the proteins tighten and squeeze out water, leaving the fondue grainy and curdled.
“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.
