Why it works: Parsley and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Chicken a LA Marengo
Ingredients
Directions
Cook the chicken
In a stewpan, heat oil and add coarse sea salt.
Add chicken pieces and cook until they are browned.
When the chicken is half done, add sliced mushrooms and truffles.
Make the sauce and serve
For the sauce, combine chopped truffles, parsley, mushrooms, shallots, and butter in a stewpan.
Stir and cook until heated through, then season with black pepper, coarse sea salt, white wine, and a couple of spoonfuls of the oil used for the chicken.
Serve the sauce hot under the cooked chicken.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chickens
- Provide the main protein, which browns in hot oil to build flavour and a firm texture.
- Truffles
- Add a strong, earthy aroma that defines the dish.
- Mushrooms
- Add moisture and savoury, meaty body to the sauce as they cook down.
- Shallots
- Add mild sweetness and aromatic depth to the sauce as they soften.
- White wine
- Adds acidity that brightens the rich butter and oil in the sauce.
- Butter
- Adds fat and richness, giving the sauce a smooth, rounded mouthfeel.
The step that matters
Browning the chicken. Chicken pieces must brown well in hot oil before the sauce is added. Browning creates flavour through the Maillard reaction, and crowding the pan causes steaming, which leaves the meat pale and bland.
Swap the parsley
How well each one fits the dish's main ingredients (chicken, mushroom, truffle, shallot, butter, pepper, white wine):
- Thymefits better
- Tarragonfits about as well
- Garlicfits about as well
- Parsleythe original
Fit is the average pairing score against chicken, mushroom, truffle, shallot, butter, pepper, white wine. Candidates are from the same food group and used in at least 100 recipes.
