Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and browns with the flour for a nutty flavour.
- Flour
- Thickens the gravy as it cooks with the liquid, giving it body.
- Milk
- Forms the liquid base that the flour thickens into a smooth gravy.
- Peanut butter
- Contributes peanut flavour and richness, and helps give the gravy a creamy texture.
The step that matters
Adding the milk and peanut butter. Whisking the milk into the browned butter and flour gradually keeps the mixture smooth, since lumps form when liquid is added too quickly to flour. Mixing until smooth lets the flour thicken the sauce evenly.
Swap the peanut
How well each one fits the dish's main ingredients (butter, flour, milk):
- Almondfits better
- Pistachiofits about as well
- Chestnutfits about as well
- Peanutthe original
Fit is the average pairing score against butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
