Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Roasted Neck of Lamb with Green Peas
Ingredients
Directions
Prepare the peas
Boil the green peas in water until tender, then drain well.
Make the sauce
Mix the peas with the béchamel sauce, onions, and parsley.
Season the mixture with salt, pepper, and sugar, then boil gently for 10 minutes.
Remove the onions and parsley, then stir in the beaten egg yolks and cream quickly.
Roast and serve
Roast the trimmed neck of lamb in vegetables, basting frequently.
When the lamb is nearly cooked, remove the vegetables and brown the lamb.
Serve the peas on a hot dish with the lamb on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Neck of lamb
- Forms the main meat; roasting and basting keep it moist and develop a browned surface.
- Green peas
- Form the bulk of the dish, providing body and a tender, sweet vegetable base.
- Béchamel sauce
- Adds creaminess and moisture, binding the peas into a smooth mixture.
- Egg yolks
- Thicken the mixture when gently heated, giving it a richer, silkier body.
- Cream
- Adds fat and richness, softening the flavour and texture of the peas.
The step that matters
Stirring in the egg yolks and cream. Egg yolks set when heated, so if the mixture is too hot or stirred slowly it can curdle or turn grainy. Adding them quickly and off strong heat keeps the sauce smooth and thickened.
Swap the peas
How well each one fits the dish's main ingredients (lamb, sauce, onion, parsley, pepper, sugar, egg):
- Chickpeafits better
- Sesamefits better
- Beansfits better
- Peasthe original
Fit is the average pairing score against lamb, sauce, onion, parsley, pepper, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
