Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Fowl
Ingredients
Directions
Prepare the fowl
Divide the remains of the fowl into small joints.
Make the gravy
Make gravy by stewing the trimmings and legs with lemon peel, mace, herbs, onion, seasoning, and water until reduced to ½ pint.
Strain the gravy and add the fowl, warming it through.
Thicken the gravy with 1 teaspoon of flour.
Finish with the cream
Stir the egg yolks into the cream and heat until hot, but do not boil.

Flour and egg barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Remains of cold fowl
- Supplies the main body of the dish, gently rewarmed in the gravy.
- Onion
- Adds savoury sweetness and aroma to the stewed gravy.
- Flour
- Thickens the gravy as its starch swells in the hot liquid.
- Cream
- Adds richness and a smooth, velvety texture to the finished sauce.
- Egg yolks
- Thicken and enrich the cream as their proteins set on gentle heating.
The step that matters
Stir the egg yolks into the cream and heat until hot, but do not boil.. Egg yolk proteins set when heated too far, so boiling would curdle the mixture into a grainy texture. Heating gently keeps it smooth and thickened.
Swap the mace
How well each one fits the dish's main ingredients (lemon, onion, pepper, flour, cream, egg):
- Parsleyfits better
- Turmericfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against lemon, onion, pepper, flour, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
