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 of the dish, softening as they stew in the gravy.
- Flour
- Thickens the gravy as it cooks, giving it body.
- Butter
- Adds richness and fat, smoothing the thickened gravy.
The step that matters
Stew gently until tender. Gentle heat softens tomatoes evenly without breaking them apart. Boiling or stacking them can cause uneven cooking and split skins, so turn them carefully.
Swap the tomato
How well each one fits the dish's main ingredients (flour, butter, pepper):
- Shallotfits better
- Chivefits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against flour, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
