Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Form the main body of the dish and become soft and sweet as they cook.
- Bread crumbs
- Add a layer that soaks up liquid and helps the top brown in the oven.
- Butter
- Adds fat and richness, helping the top brown and the flavour feel fuller.
- Cream or milk
- Adds moisture that softens the layers and helps set them into a tender, custardy texture.
The step that matters
Cook the onions in water for a few minutes. Brief pre-cooking softens the onions so they become tender during baking. Draining well matters, because excess water thins the liquid and keeps the dish from setting and browning properly.
Swap the onion
How well each one fits the dish's main ingredients (bread, pepper, butter, cream):
- Potatofits about as well

- Onionthe original
Fit is the average pairing score against bread, pepper, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
