Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the main body of the dish and release juices that become the stewed sauce.
- Sugar
- Adds sweetness that balances the tomatoes' natural acidity.
- Butter
- Adds fat and richness, giving the sauce a smoother, rounder mouthfeel.
- Flour
- Thickens the cooking juices as its starch swells in the hot liquid.
The step that matters
Add butter cut into flour. Flour thickens the juices only when its starch is evenly dispersed and heated. Added in clumps or unstirred, it stays lumpy and leaves pockets of raw flour taste, so it should be worked through the liquid before the final simmer.
Swap the tomato
How well each one fits the dish's main ingredients (sugar, pepper, butter, flour):
- Capsicumfits better
- Arrowrootfits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against sugar, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
