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 Franqatse, or French Fashion
Ingredients
Directions
Prepare the peas
Place the peas in a pot of spring water with the butter and mix until the butter coats the peas.
Drain the peas in a colander and transfer them to a thick saucepan without any water.
Cook
Cook over gentle 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 the sugar and a smooth mixture of ½ ounce butter and 1 teaspoon flour.
Shake over the fire for 2 minutes and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young peas
- The main ingredient, cooked until tender and forming the body of the dish.
- Butter
- Coats the peas and adds richness and a smooth, silky mouthfeel.
- Flour
- Thickens the cooking liquid into a smooth, lightly bound sauce.
- Sugar
- Adds a touch of sweetness that balances the savoury flavour of the peas.
The step that matters
Boil quickly for 40 minutes. Peas must be cooked long enough to soften fully, but a rolling boil can break them apart and toughen the skins. Keep the heat controlled and check that the water has not boiled away, since the peas need just enough liquid to stay moist.
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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
