Why it works: Pepper and parsley 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 ↓
Pur&E of Peas
Ingredients
Directions
Prepare the peas
Wash the peas in cold water.
Place the washed peas in a saucepan with cold water.
Bring the peas to a boil.
If using canned peas, boil for 20 minutes; if using dried peas, boil for 2 hours or until tender.
When done, the water should be almost absorbed.
Press the peas through a colander.
Make the milk and thickening
Meanwhile, boil the milk in a separate pot with the bay leaf, chopped onion, cloves, parsley, and ham for 20 minutes.
Rub the butter and flour together until smooth.
Finish and serve
Strain the boiled milk into the pressed peas.
Return the mixture to the pot.
Stir in the flour and butter mixture.
Continue stirring until it thickens and boils for 3 minutes.
Add salt and pepper to taste.
Serve with veal cutlets or mutton chops.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the main body of the puree once cooked and pressed smooth.
- Milk
- Adds moisture and richness, softening the puree into a creamy texture.
- Butter and flour
- Form a roux-style paste that thickens the puree when stirred in.
- Ham
- Flavours the milk with savoury, smoky depth during the infusion.
- Onion
- Adds aromatic sweetness and savour to the infused milk.
The step that matters
Stirring in the butter and flour mixture. Flour thickens only when heated while stirred and brought to a boil; stopping early leaves the puree thin and floury-tasting, while stirring constantly prevents lumps from forming.
Swap the peas
