Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Puree of Green Peas
Ingredients
Directions
Prepare the peas
Shell the peas and set them aside in a cold place.
Boil the pods in enough salted water to cover them for 20 minutes.
Strain the pods and return the water to the fire with the peas and a sprig of mint.
Boil until the peas are soft enough to rub through a colander.
Make the puree
Press the peas through the colander, stirring in 1 cup of the cooking water.
Season with pepper and salt, then return to the colander.
In a separate pan, cook 1 tablespoon of flour in 2 tablespoons of butter for 3 minutes.
Stir the roux into the peas and cook for 1 minute.
Remove from heat and add 3 tablespoons of heated cream mixed with a tiny bit of baking soda.
Serve
Serve the puree over squares of fried bread on a hot platter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Provide the main body and flavour, becoming a smooth puree once cooked and pressed.
- Flour
- Cooked with butter into a roux, it thickens the puree as it is stirred in.
- Butter
- Cooks with the flour into a roux and adds richness and a silky mouthfeel.
- Cream
- Adds richness and smoothness, softening the puree's texture at the end.
- Baking soda
- Added in tiny amounts to the cream, it is included in the record as a small addition.
The step that matters
Stir the roux into the peas and cook for 1 minute. Flour must be cooked in fat before liquid is added to avoid a raw, pasty taste. Brief cooking after adding it lets the starch thicken the puree and cook out the floury flavour.
Swap the peas
How well each one fits the dish's main ingredients (pepper, flour, butter, cream, bread):
- Almondfits better
- Chestnutfits better
- Pistachiofits better
- Peasthe original
Fit is the average pairing score against pepper, flour, butter, cream, bread. Candidates are from the same food group and used in at least 100 recipes.
