Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baked beans
- Provide the main body and starch that thicken the soup when simmered and sieved.
- Butter or drippings
- Add fat and richness, carrying flavour through the soup.
- Flour
- Thickens the soup when cooked with the fat before being stirred in.
- Tomatoes
- Add acidity and colour, balancing the sweetness of the beans.
The step that matters
Cooking the butter or drippings with the flour. Cooking fat and flour together into a roux removes raw flour taste and lets the flour thicken smoothly without lumps when stirred into the hot soup.
Swap the onion
How well each one fits the dish's main ingredients (beans, butter, flour, tomato, pepper):
- Okrafits better
- Capsicumfits better
- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against beans, butter, flour, tomato, pepper. Candidates are from the same food group and used in at least 100 recipes.
