Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Sauce
Ingredients
Directions
Prepare the base
Wash and peel the carrot, turnip, and onion.
Cut them into small pieces and place in a stewpan with the bouquet garni, peppercorns, cloves, veal, and ham.
Add 2 tablespoons of butter and stir over medium heat until light brown to create a mirepoix.
Pour off the fat and moisten the mirepoix with stock, claret, sherry, and tomato pulp.
Boil gently for about an hour, skimming occasionally.
Make the roux
Meanwhile, prepare a brown roux by melting 3 oz. of butter in a stewpan.
Stir in the flour and cook slowly over medium heat, stirring constantly until it turns chestnut brown.
Allow the roux to cool slightly.
Finish and store
Gradually pour in the prepared stock mixture, stirring until it boils.
Let it simmer slowly for another hour, skimming well.
Pass the sauce through a fine sieve.
If too thick, add more stock.
Stir occasionally until cool to prevent a crust from forming.
Store the sauce in a stone vessel.
Boil it daily if not used, adding stock if necessary.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce when cooked in butter as a roux.
- Butter
- Enriches the mirepoix and roux, carrying flavour and helping browning.
- Stock
- Forms the liquid body of the sauce and sets its consistency as it reduces.
- Tomato pulp
- Adds acidity and colour to the sauce.
- Veal
- Contributes meaty flavour and body to the stock base.
The step that matters
Cooking the roux to chestnut brown. Cooking flour in fat until it browns develops nutty flavour and colour, but if it is undercooked the sauce tastes raw and floury, and if it scorches it turns bitter. Stirring constantly keeps the heat even.
Swap the clove
How well each one fits the dish's main ingredients (carrot, turnip, onion, veal, ham, butter, sherry):
- Parsleyfits better
- Celeryfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against carrot, turnip, onion, veal, ham, butter, sherry. Candidates are from the same food group and used in at least 100 recipes.
