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 ↓
Art of Preserving
Ingredients
Directions
Make the sauce
In a saucepan, melt the butter over medium heat.
Add the parsley and chives, tossing them in the butter.
Sprinkle in the flour and quickly add boiling water until it covers the peas.
Boil for 15 minutes until the sauce thickens.
Season with salt and pepper, then cook until reduced.
Finish and serve
Remove from heat and stir in the fresh butter and powdered sugar.
Serve the peas in a warm dish, shaped like a pyramid.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the main body of the dish and absorb the flavour of the sauce.
- Flour
- Thickens the cooking liquid into a sauce as it boils.
- Fresh butter
- Adds richness and a smooth, glossy finish to the sauce.
- Powdered sugar
- Adds a touch of sweetness that balances the savoury herbs.
The step that matters
Sprinkle in the flour and add boiling water quickly. Adding flour directly to hot butter and then stirring in liquid helps prevent lumps, because the flour coats evenly before it hydrates. Adding the water quickly keeps the mixture smooth as it thickens.
Swap the peas
How well each one fits the dish's main ingredients (butter, parsley, chive, flour, pepper, sugar):
- Chestnutfits better
- Chickpeafits better
- Lentilsfits better
- Peasthe original
Fit is the average pairing score against butter, parsley, chive, flour, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
