Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften when boiled and mashed, forming the body and sweet base of the stew.
- Cheese
- Melts into the onions, adding richness and a savoury, creamy texture.
- Butter
- Adds fat that carries flavour and helps the cheese blend smoothly into the stew.
The step that matters
Stir the cheese into the hot onions. Cheese can turn stringy or grainy if it overheats or melts too fast. Stirring over gentle heat for a short time helps the fat and proteins emulsify into a smooth, cohesive stew.
Swap the onion
How well each one fits the dish's main ingredients (cheese, butter, pepper, bread):
- Capsicumfits better
- Tomatofits better
- Potatofits about as well
- Onionthe original
Fit is the average pairing score against cheese, butter, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
