Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Its starch thickens the liquid as it heats, giving the soup body.
- Milk or cream
- Forms the liquid base and adds richness and a smooth, creamy texture.
The step that matters
Boil the mixture well. Flour starch only thickens fully once the liquid reaches a boil, and boiling cooks out the raw floury taste. Mixing the flour into cold milk until smooth first helps prevent lumps.
Swap the mace
How well each one fits the dish's main ingredients (flour, milk, pepper):
- Cardamomfits better
- Cinnamonfits better
- Turmericfits better
- Macethe original
Fit is the average pairing score against flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
