Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Proteins set as they heat, thickening the mixture into a creamy base.
- Butter
- Adds fat that makes the fondue smooth and rich in texture.
- Cheese
- Melts into the mixture, providing the main flavour and stretchy body.
The step that matters
Cook for about 7 minutes, ensuring it boils but does not set.. Egg proteins thicken with heat but curdle if overheated. Constant stirring and gentle heat keep the mixture smooth instead of grainy or scrambled.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, butter, cheese):
- Nutmegfits better
- Parsleyfits better
- Capersfits better
- White pepperthe original
Fit is the average pairing score against egg, butter, cheese. Candidates are from the same food group and used in at least 100 recipes.
