Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal or poultry trimmings gravy
- Provides the savory liquid base and most of the gravy's flavor.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the gravy.
- Potato flour
- Thickens the gravy, as its starch swells when heated in liquid.
The step that matters
Stir the flour in evenly. Potato flour is a starch that swells when heated in liquid. If it is not stirred in evenly, it clumps and the gravy thickens unevenly. Keep stirring until the gravy thickens.
Swap the potato
How well each one fits the dish's main ingredients (veal, butter, flour):
- Shallotfits better
- Leekfits better
- Chivefits better
- Potatothe original
Fit is the average pairing score against veal, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
