Why it works: Beef and chicken match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 2,148 recipes. Both carry 2-furfurylthiol, which smells coffee, roasted. The science ↓
Stock Fob Brown Sauce
Ingredients
Directions
Prepare the stock
Combine shredded onions, sliced carrot, and tomatoes (or tomato puree with sugar) in a stock pot.
Add ham fat and a little dripping, then simmer for 15 minutes without coloring.
Add beef, veal, and fill the pot with 2 gallons of water.
Add bouquet garni, celery, and peppercorns.
Boil for 5 hours, skimming off fat and replenishing with boiling water as needed.
Strain the stock through a coarse strainer and let it sit overnight to allow the fat to rise.
Remove the fat and bring the stock to a boil in a clean pot.
Thicken and colour
In a bowl, dissolve fecule flour in Sherry (or other liquid).
Stir the boiling stock continuously while slowly adding the dissolved mixture until it thickens.
Remove from heat and let it boil quietly for 2–3 minutes.
Add coloring until a light brown is achieved, then strain through fine muslin.
Cool and keep
Transfer the sauce to a large basin and stir occasionally until cool to prevent fermentation.
Boil the mixture and transfer to a clean basin every second day to keep it fresh.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Knuckle of beef
- Releases gelatin and flavor into the stock during the long simmer, giving body.
- Knuckle of veal
- Adds gelatin from its bones and connective tissue, giving the stock a fuller body.
- Fecule flour or arrowroot
- Starch that thickens the boiling stock into a smooth, glossy sauce.
- Tomatoes
- Add acidity and a reddish note that balances the rich meat flavor.
- Onions
- Build savory aromatic flavor as they cook slowly into the stock.
The step that matters
Stirring while adding the starch mixture. Starch added to boiling liquid without constant stirring can clump and thicken unevenly. Adding it slowly while stirring disperses the granules so the sauce becomes smooth.
Swap the carrot
How well each one fits the dish's main ingredients (beef, veal, ham, chicken, onion, tomato, sugar):
- Capsicumfits better
- Potatofits about as well
- Carrotthe original
- Okrafits about as well
Fit is the average pairing score against beef, veal, ham, chicken, onion, tomato, sugar. Candidates are from the same food group and used in at least 100 recipes.
