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
Place peas in a pot with plenty of spring water and 2 ounces of butter. Mix until butter coats the peas.
Drain the peas in a colander.
Transfer them to a thick saucepan without water.
Cook
Cook over gentle heat, stirring occasionally for 20 minutes until they begin to simmer.
Add enough boiling water to just cover the peas and a pinch of salt.
Boil quickly for 40 minutes.
Thicken and serve
Mix a small lump of sugar dipped in water and ½ ounce of butter with 1 teaspoon of flour. Stir this mixture into the peas.
Shake the peas over the heat for 2 minutes.
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 of the dish, cooking down until tender.
- Butter
- Adds richness and a glossy coating that keeps the peas from drying out.
- Flour
- Thickens the cooking liquid into a light, smooth sauce when stirred in with butter.
The step that matters
Stirring the butter and flour into the peas. Flour mixed with butter forms a paste that thickens the liquid when stirred in. Shaking the peas over heat for the final 2 minutes helps cook out the raw flour taste and keeps the sauce from clumping.
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.
