Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main flesh and body that gives the sauce its rich, savory character.
- Flour
- Thickens the sauce so it coats the back of a spoon.
- Butter
- Adds fat and smoothness to the thickened sauce.
- Anchovies
- Contribute salty, savory depth that builds the sauce's flavor.
The step that matters
Let it simmer until rich. Simmering gently extracts flavor and gelatin from the eels and bones slowly; a hard boil can cloud the liquid and make it greasy or bitter. Stop when the liquid tastes concentrated before thickening.
Swap the mace
How well each one fits the dish's main ingredients (bread, pepper, flour, butter):
- Parsleyfits better
- Nutmegfits better
- Sagefits better
- Macethe original
Fit is the average pairing score against bread, pepper, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
