Why it works: Parsley and marjoram match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,979 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓

Directions
Brown the butter in a saucepan over a clear fire.
Heat the cup of liquor to a boil, then skim and season with salt and pepper.
Skim again before stirring in the flour mixed with cold water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Browned flour
- Thickens the liquor into a smooth sauce as it cooks.
- Butter
- Adds richness and a nutty flavor when browned, and body to the finished sauce.
- Onion vinegar
- Adds acidity that brightens the rich, savory sauce.
- Made mustard
- Adds a sharp, pungent note that balances the richness.
The step that matters
Skim again before stirring in the flour mixed with cold water. Skimming removes foam and fat that would otherwise cloud the sauce and leave an unpleasant surface. Flour mixed with cold water disperses evenly before heating, which prevents lumps as the starch thickens the liquid.
Swap the onion
How well each one fits the dish's main ingredients (butter, mustard, pepper, flour, parsley, marjoram, vinegar):
- Shallotfits better
- Horseradishfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against butter, mustard, pepper, flour, parsley, marjoram, vinegar. Candidates are from the same food group and used in at least 100 recipes.
