Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the liquid as its starch swells with heat, giving the sauce body.
- Butter
- Adds richness and a smooth mouthfeel to the sauce.
- Molasses
- Provides sweetness and deep flavor, along with color.
- Milk
- Forms the creamy liquid base that the sauce thickens into.
The step that matters
Whisking the flour in until smooth. Flour clumps if it hits hot liquid unevenly, and lumps are hard to remove later. Whisking it into the cold liquid first disperses the starch so it thickens evenly as the sauce heats.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, flour, butter, molasses):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Clovefits less well
Fit is the average pairing score against milk, flour, butter, molasses. Candidates are from the same food group and used in at least 100 recipes.
