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.
Simmer and thicken
Drain off the butter and add the stock, tomato sauce, and sherry.
Bring to a boil and cook for 1 hour.
Stir in the brown roux with a wooden spoon until it boils.
Continue boiling for 1 hour or until a nice brown color is achieved.
Add more stock if the sauce becomes too thick.
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 cooks.
- Veal
- Adds meaty flavor that deepens during the long simmer.
- Ham hock
- Contributes savory, smoky depth to the stock base.
- Tomato sauce
- Adds acidity and color, balancing the richness of the sauce.
- Stock
- Forms the liquid body of the sauce and carries its flavor.
- Onions
- Provide sweetness and aroma as they brown in the butter.
The step that matters
Stir in the brown roux and keep it boiling. Roux thickens only when it reaches a boil, and the starch needs to cook fully to lose its raw taste. Stirring prevents lumps and scorching on the base of the pan.
