Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Drawn Butter
Ingredients
Directions
Make the drawn butter
In a bowl, rub together the flour and butter until well mixed.
Transfer the mixture to a saucepan and add the milk or water.
Place the saucepan in a double boiler and stir well until it comes to a boil.
Add the vegetables
If using vegetables, boil them first, mince, and gradually add to the drawn butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat and rich flavor, forming the body of the sauce as it melts.
- Flour
- Thickens the butter as it heats, giving the sauce body and a smooth texture.
- Milk or water
- Loosens the flour-butter mixture into a pourable liquid sauce.
The step that matters
Stirring while heating in the double boiler. Gentle, constant stirring over indirect heat keeps the flour evenly dispersed and prevents lumps or scorching. Direct high heat can separate the butter fat and burn the milk solids, so the sauce turns grainy or bitter.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (butter, flour, milk, parsley, celery, mint):
- Carrotfits better
- Leekfits better
- Parsnipfits better
- Onionthe original
Fit is the average pairing score against butter, flour, milk, parsley, celery, mint. Candidates are from the same food group and used in at least 100 recipes.
