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 ↓

Make the fondue

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a thick, custard-like base that holds the melted cheese together.
- Gruyere cheese
- Melts into the eggs to add rich flavour and a creamy, stretchy texture.
- Butter
- Adds fat for silkiness and richness, helping the mixture stay smooth as it heats.
The step that matters
Stirring over medium heat. Eggs set quickly and can turn grainy or scrambled if overheated. Gentle, constant stirring keeps the mixture smooth and creamy, so it stops just at the point where it is set but not hard.
