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 ↓
Chicken a LA Marengo
Ingredients
Directions
Brown the chicken
Heat the oil in a pan and test it with a crust of bread.
Sauté the chicken joints in the oil, adding the legs first for 5 minutes.
Add the chopped onions and herbs, cooking until the chicken is light brown.
Make the sauce and serve
Drain off excess oil and prepare a sauce with mushrooms and lemon juice or tomato purée.
Arrange the chicken on a serving dish, placing the delicate pieces on top.
Surround with croutons and crayfish if available.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Forms the main body of the dish, cooked by browning in oil until golden.
- Oil
- Conducts heat for browning the chicken and carries flavour through the pan.
- Onions
- Soften and sweeten as they cook, adding savoury depth to the sauce base.
- Mushrooms
- Add earthy flavour and moisture to the sauce.
- Lemon juice
- Adds acidity that brightens the sauce and balances the richness of the chicken.
- Tomato purée
- Adds concentrated tomato flavour and body to the sauce.
The step that matters
Browning the chicken joints. Browning in hot oil creates colour and savoury flavour through the Maillard reaction. Pieces crowded or cooked in oil that is not hot enough will steam and turn pale instead.
Swap the onion
