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 ↓
Espagnole Sauce
Ingredients
Directions
Prepare the base
In a stewpan, combine the carrots, onions, veal, ham, parsley, peppercorns, and butter.
Stir over high heat until lightly browned.
Drain off the butter and add the stock, tomato sauce, and sherry.
Simmer and thicken
Bring to a boil and let it simmer for 1 hour.
Stir in the brown roux with a wooden spoon until it boils.
Continue boiling for another hour or until it reaches a nice brown color.
If the sauce becomes too thick, add a little more stock.
Strain and store
Strain through a fine cloth, remove all fat, and transfer to a basin for use.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown roux
- Thickens the sauce and gives it body as it boils.
- Veal
- Contributes savory meaty flavor to the stock as it browns and simmers.
- Onions
- Caramelize during browning, adding sweetness and depth to the sauce.
- Carrots
- Add gentle sweetness and aromatic body as they brown with the other vegetables.
- Tomato sauce
- Adds acidity and color, rounding out the sauce's flavor.
- Stock
- Forms the liquid base that the sauce reduces and thickens in.
The step that matters
Stir in the brown roux and keep it boiling. Roux thickens only when heated enough for its starch to swell, and it can lump if added without steady stirring. Boiling for the full time also cooks out raw flour taste and lets the color deepen.
