Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Forms the fat base of the roux and adds richness to the sauce.
- Flour
- Thickens the sauce as its starch swells in the hot liquid.
- Veal stock
- Provides the savoury liquid body and meaty flavour of the sauce.
- Cream
- Adds richness and a smooth, silky texture to the sauce.
The step that matters
Cook the flour without browning. Flour must be cooked in the fat long enough to lose its raw starchy taste, but browning changes its colour and flavour and weakens the sauce's pale, delicate character. Gentle heat and constant stirring keep the roux pale while it cooks through.
Swap the walnut
How well each one fits the dish's main ingredients (butter, flour, veal, cream, pepper, carrot, parsley):

Fit is the average pairing score against butter, flour, veal, cream, pepper, carrot, parsley. Candidates are from the same food group and used in at least 100 recipes.
