Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
White Sauce
Ingredients
Directions
Make the broth
Combine the knuckle of veal, ham, cloves, mace, bay leaves, parsley, thyme, onion, carrot, and turnip with water in a pot.
Simmer until the broth is flavorful.
Make the sauce
Melt butter in a separate pan, then add flour according to the amount of sauce desired.
Cook the flour briefly, then gradually stir in the strained broth until well mixed.
Bring to a boil and cook for 1 hour, then strain again.
Heat the sauce, add enough cream to make it rich and white, and boil quickly while stirring until thickened.
Optionally add a squeeze of lemon juice before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries the flour so it cooks smoothly into a roux.
- Flour
- Thickens the broth into a sauce once cooked briefly with the butter.
- Cream
- Adds richness and whiteness, and lends a smooth, silky texture to the finished sauce.
- Knuckle of veal
- Gives the broth body and savory depth as it simmers.
The step that matters
Adding the broth to the roux. Stirring the broth in gradually while the flour is cooked keeps the mixture smooth. Adding it all at once can leave lumps of flour that are hard to remove.
Swap the mace
How well each one fits the dish's main ingredients (veal, ham, clove, parsley, thyme, onion, carrot):
- Marjoramfits better
- Winter savoryfits better
- Celeryfits better
- Macethe original
