Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and tart flavour of the sauce, softening as they boil.
- Flour
- Thickens the liquid when browned in fat and stirred into it.
- Sugar
- Adds sweetness that balances the acidity of the tomatoes and lemon juice.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sugar.
The step that matters
Browning the flour. Flour cooked in fat until golden loses its raw taste and thickens better, while stirring prevents lumps from forming when the liquid is added.
Swap the onion
How well each one fits the dish's main ingredients (tomato, sugar, lemon, mustard, ginger, cinnamon, parsley):
- Broccolifits better
- Shallotfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against tomato, sugar, lemon, mustard, ginger, cinnamon, parsley. Candidates are from the same food group and used in at least 100 recipes.
