Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts into the liquid to give the sauce its rich flavour and smooth body.
- Flour
- Thickens the boiling water into a smooth, pourable sauce.
- Parsley
- Adds fresh, green aroma at the end of cooking.
The step that matters
Adding the boiling water while stirring constantly. Flour clumps if liquid is added all at once or without stirring. Constant stirring disperses the starch granules evenly, so the sauce thickens smooth rather than lumpy.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, flour):
- Capersfits better
- Nutmegfits better
- Jalapenofits about as well
- Parsleythe original
Fit is the average pairing score against egg, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
