Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender, delicate meat that forms the main body of the dish.
- Butter
- Adds richness and flavor, and with flour helps thicken the gravy.
- Flour
- Thickens the gravy when cooked with butter, giving it body.
- Stewed tomatoes
- Supply acidity and moisture, forming the tomato base of the gravy.
The step that matters
Adding the flour and butter mixture to the gravy. If the flour is not cooked enough or is added unevenly, it can leave lumps or a raw starchy taste. Stirring it in smoothly and simmering lets the starch hydrate and thicken the gravy evenly.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, flour, butter):
- Shallotfits better
- Chivefits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against pepper, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
