Why it works: Lemon and parsley 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 ↓
Boiled Fowl with Egg Sauce
Ingredients
Directions
Prepare the fowl
Truss the fowl and rub it with a little lemon juice.
Wrap the fowl in buttered paper or cloth and boil according to its size.
Make the sauce
In a saucepan, melt the butter, then stir in the flour to make a roux.
Gradually add the broth and milk, stirring until smooth.
Separate the egg whites from the yolks and chop the whites.
Add the chopped egg whites, pepper, salt, and lemon juice to the sauce.
Serve
Remove the fowl from the pot, drain, and place it on a serving dish.
Pour the sauce over the fowl and rub the egg yolks through a coarse wire sieve on top.
Optionally, rub the liver of the fowl through the sieve onto the breast.
Garnish the dish with lemon and parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowl
- Forms the main dish; boiling cooks it through while keeping the meat moist and tender.
- Butter
- Enriches the sauce and, with flour, forms the roux that thickens it.
- Flour
- Thickens the sauce by forming a roux with the melted butter.
- Broth
- Adds savoury flavour to the sauce and loosens it into a pourable consistency.
- Milk
- Makes the sauce smooth and creamy, softening its flavour.
- Eggs
- Contribute richness and body to the sauce; the chopped whites add texture and the yolks give a soft, creamy finish.
The step that matters
Stirring the sauce while adding the broth and milk. Adding liquid to a roux gradually while stirring keeps the flour dispersed, so the sauce becomes smooth rather than lumpy as the starch thickens.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, flour, milk, lemon, pepper):
- Parsleythe original
- Nutmegfits about as well
- Cardamomfits about as well
- Cinnamonfits less well
Fit is the average pairing score against egg, butter, flour, milk, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
