Why it works: Carrot and onion are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 21,601 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Bechamel Sauce
Ingredients
Directions
Make the broth
Cut up the carcase of the fowl and place it in a saucepan with the bacon bones.
Add veal or gelatine, carrot, onion, mace, peppercorns, and salt.
Pour in enough water to cover the ingredients and simmer gently for 2 hours.
Strain the broth and skim off any grease, reducing it to about ¾ cup.
Finish the sauce
Mix the reduced broth with an equal quantity of boiling cream and thicken with arrowroot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold fowl carcase
- Provides the main meaty flavour and body for the broth that forms the sauce base.
- Cream
- Adds richness and a smooth, silky texture to the sauce.
- Arrowroot
- Thickens the liquid into a glossy sauce as it is heated.
- Veal or gelatine
- Adds body and a lightly gelled richness to the broth.
The step that matters
Thickening with arrowroot. Arrowroot thickens only when the liquid is hot, and it can break down or turn thin if overheated or boiled too long, so the sauce should be heated gently just until it thickens.
Swap the mace
How well each one fits the dish's main ingredients (veal, carrot, onion, cream, arrowroot):
- Celeryfits better
- Turmericfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against veal, carrot, onion, cream, arrowroot. Candidates are from the same food group and used in at least 100 recipes.
