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 ↓
Mince Herb Sauce
Ingredients
Directions
Make the sauce
In a stewpan, heat the oil and sauté the onions for a few minutes.
Add the demi-glaze and broth or water; bring to a boil and skim off any scum.
If the sauce is too thick and scum does not rise, add ½ cup of broth or water.
Boil and reduce to the desired thickness.
Finish and serve
Stir in the chopped parsley, mushrooms, cayenne pepper, and lemon juice.
Serve warm, optionally adding a little garlic.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Demi-glaze
- Provides the rich, concentrated body and savory depth that forms the base of the sauce.
- Onions
- Softened by sautéing, they add mild sweetness and aromatic flavor to the sauce.
- Mushrooms
- Add earthy flavor and a slightly meaty texture to the finished sauce.
The step that matters
Skim off the scum after the sauce comes to a boil. Scum that rises when the liquid boils is impurities from the stock and demi-glaze; removing it keeps the sauce clear and clean-tasting. Skimming early, before reducing, prevents those impurities from concentrating into the final sauce.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (onion, mushroom, pepper, lemon, garlic):
- Thymefits better
- Parsleythe original
- Marjoramfits about as well
- Oreganofits less well
Fit is the average pairing score against onion, mushroom, pepper, lemon, garlic. Candidates are from the same food group and used in at least 100 recipes.
