Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cheese
- Melts into the sauce to provide its rich body and savoury flavour.
- Olive oil
- Adds fat that helps the sauce stay smooth and coat the palate.
- Dry mustard
- Contributes a sharp, pungent aroma that cuts the richness of the cheese.
- Ale
- Thins the melted cheese into a pourable sauce and adds malty flavour.
The step that matters
Keep the cheese melting gently. Cheese proteins toughen and separate when overheated, turning the sauce grainy and oily. Low, gentle heat keeps it smooth. Stir the ale in until fully combined so the sauce stays uniform.
Swap the mustard
How well each one fits the dish's main ingredients (cheese, olive, pepper):
- Capsicumfits better
- Tomatofits better
- Mustardthe original
- Spinachfits about as well
Fit is the average pairing score against cheese, olive, pepper. Candidates are from the same food group and used in at least 100 recipes.
