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, onion, leek, sweet herbs, allspice, black pepper, mace, lemon peel, and bay leaves in a pan.
Add 4 cups of water and cook over medium heat until light brown, being careful not to burn.
Add enough beef broth to cover the ingredients and bring to a boil.
Make the gravy
Skim off any fat and thicken the mixture with flour and butter.
Simmer gently for 45 minutes.
Season with Cayenne pepper, lemon juice, and coarse sea salt.
Strain through a sieve and add a little coloring liquid.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the gravy as it cooks, giving it a body that clings to food.
- Butter
- Adds richness and helps the flour blend smoothly into the liquid as a thickener.
- Veal
- Contributes gelatin and savory meat flavor that gives the gravy body and depth.
- Ham
- Adds salty, smoky meat flavor that seasons the whole gravy.
The step that matters
Cook the ingredients until light brown without burning. Browning the meat and vegetables builds deep, roasted flavor through the Maillard reaction. Burnt solids, however, turn bitter and can spoil the whole gravy, so heat must stay moderate and the pan should be watched closely.
Swap the allspice
How well each one fits the dish's main ingredients (ham, veal, celery, carrot, turnip, onion, leek):
