Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the base; folded whites lighten and puff the fondue as it bakes.
- Cheese
- Melts into the sauce to give the fondue its rich flavour and body.
- Flour
- Thickens the milk and butter into a smooth sauce base.
- Milk
- Forms the liquid base that the flour thickens.
- Butter
- Adds fat and richness to the sauce base.
The step that matters
Cool the sauce before adding the egg yolks. If the sauce is too hot, the yolks can scramble instead of blending smooth, so letting it cool slightly protects the texture.
Swap the mustard
How well each one fits the dish's main ingredients (cheese, butter, egg, milk, flour, pepper):
- Potatofits better
- Capsicumfits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against cheese, butter, egg, milk, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
