Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 8,053 recipes mention both. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Espagnole or Brown Sauce
Ingredients
Directions
Make the base
In a stewpan, combine the carrot, onion, beef or veal, ham or bacon, parsley, celery, bay leaf, peppercorns, mace, savory herbs, and butter.
Boil over high heat until light brown.
Strain off the fat, then add the stock, tomato conserve, and red wine.
Simmer for one hour.
Make the sauce
In another stewpan, melt the butter or dripping, then add the flour and stir over low heat until brown.
Strain the prepared stock, skim well, and gradually add it to the browned flour.
Stir until it boils, then let it simmer for at least twenty minutes.
If the sauce is too thick, add a little more stock.
Season to taste, then skim and strain before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef or veal
- Adds meaty depth and savoury flavour to the stock as it browns and simmers.
- Flour
- Browned in fat, it thickens the sauce and adds a toasted, nutty flavour.
- Butter or dripping
- Carries the flour's browning and adds richness and fat to the sauce.
- Stock
- Forms the liquid base of the sauce, giving body and savoury flavour.
- Tomato conserve
- Adds acidity, colour and a rounded sweet-savoury tang to the sauce.
- Onion
- Caramelises when browned, adding sweetness and aromatic depth to the stock.
The step that matters
Browning the flour. Flour cooked in fat must be stirred over low heat until evenly brown. Undercooked flour tastes raw and pasty, while overheated flour turns bitter and dark, so the sauce's flavour and colour depend on this step.
Flavor stand-ins for the mace
How well each one fits the dish's main ingredients (carrot, onion, beef, ham, parsley, celery, butter):

- Macethe original
Fit is the average pairing score against carrot, onion, beef, ham, parsley, celery, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
