Why it works: Turnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Cullis, or a Thick Gravy
Ingredients
Directions
Prepare
Combine ham, veal, celery, carrots, turnips, onions, leeks, herbs, allspice, black pepper, mace, lemon peel, and bay leaves with 4 cups of water in a pan.
Cook over medium heat until light brown, being careful not to burn it.
Make the gravy
Add enough beef stock to cover the mixture and bring to a boil.
Skim off any fat and thicken with a mixture of flour and butter.
Let it simmer gently for 45 minutes, seasoning with cayenne pepper, lemon juice, and salt to taste.
Strain and serve
Strain through a fine sieve or cloth before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the liquid into a smooth, body-rich gravy when cooked with the butter.
- Butter
- Combines with the flour to form a roux that thickens the gravy and adds richness.
- Beef stock
- Forms the liquid base that carries the flavor and becomes the body of the gravy.
- Ham
- Adds savory, salty depth to the stock as it simmers.
- Veal
- Contributes gelatin and meaty flavor that give the gravy body and richness.
- Onions
- Add sweetness and aromatic depth when browned with the meats.
The step that matters
Cook the vegetables and meats until light brown. Browning builds deep, roasted flavor through the Maillard reaction, but scorching adds bitter, burnt notes that carry into the gravy, so heat must stay moderate and the pan must be watched closely.
Swap the allspice
How well each one fits the dish's main ingredients (ham, veal, celery, carrot, turnip, onion, leek):
