Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grated cheese
- Melts into a smooth, stretchy base that forms the body of the dish.
- Butter
- Adds fat that helps the cheese melt smoothly and gives a richer mouthfeel.
- Prepared mustard
- Adds sharp, tangy flavour that balances the richness of the cheese.
- Brown stout or port wine
- Adds depth and roasted or sweet notes, and thins the mixture as it heats.
The step that matters
Browning the mixture. Cheese and sugars in the wine brown quickly under heat. Browning relies on the Maillard reaction, which needs enough heat for flavour, but too much heat scorches the cheese and makes it bitter and oily.
Swap the mustard
How well each one fits the dish's main ingredients (butter, cheese, pepper, port wine):
- Capsicumfits better
- Mustardthe original
- Potatofits about as well
- Tomatofits about as well
Fit is the average pairing score against butter, cheese, pepper, port wine. Candidates are from the same food group and used in at least 100 recipes.
