Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Green Peas a LA Franqaise, or French Fashion
Ingredients
Directions
Prepare the peas
In a large pot, combine the peas and butter, and mix until the butter coats the peas.
Drain the peas in a colander and place them in a thick saucepan without any water.
Cook the peas
Cook over low heat, stirring occasionally, for 20 minutes until they begin to simmer.
Add boiling water to just cover the peas and a small amount of salt.
Boil quickly for 40 minutes.
Finish and serve
Mix in a small lump of sugar dipped in water and a smooth mixture of ½ ounce butter and 1 teaspoon flour.
Shake over the heat for 2 minutes and serve immediately in a hot dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young peas
- Provide the main body and sweet, delicate flavor of the dish.
- Butter
- Adds richness and a silky mouthfeel to the peas and the sauce.
- Flour
- Thickens the cooking liquid into a smooth, lightly bound sauce.
The step that matters
Shake over the heat after adding the butter and flour mixture. Flour needs heat and movement to cook out its raw taste and thicken evenly. Stirring in the paste and keeping the pan moving prevents lumps and a pasty flavor.
Swap the peas
How well each one fits the dish's main ingredients (butter, sugar, flour):
- Almondfits better
- Macadamia nutfits better
- Chestnutfits better
- Peasthe original
Fit is the average pairing score against butter, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
