Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Supreme Sauce
Ingredients
Directions
Make the sauce
Heat the stock in a saucepan until hot.
Thicken the stock with white roux, stirring until smooth and it coats the spoon.
Add herbs and seasoning
Blanch the herbs in scalding water for 2 minutes, then drain and finely mince them.
Stir 2 teaspoons of the chopped herbs into the sauce, along with salt and white pepper.
Before serving, carefully add 2 teaspoons of strained lemon juice to the sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal and chicken stock
- Forms the liquid base that the roux thickens into a sauce.
- White roux
- Thickens the stock so the sauce coats the spoon.
- Parsley, cress, and tarragon leaves
- Provide fresh herbal flavour and colour to the finished sauce.
- Strained lemon juice
- Adds acidity that brightens the flavour of the sauce.
The step that matters
Adding the lemon juice before serving. Acid added late keeps its bright flavour; heating it for long can dull the taste. Adding it carefully and near the end keeps the sauce fresh and balanced.
Swap the white pepper
How well each one fits the dish's main ingredients (veal, chicken, parsley, tarragon, lemon):
- Marjoramfits better
