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
Ingredients
Directions
Prepare
Pick and wash the peas in cold water, then drain them in a colander.
Cook
In a stew pan, combine the peas and cold water, and bring to a boil for 30 minutes.
Add parsley, sugar, and salt to the peas.
Mix butter and flour together, then stir into the peas.
Let the mixture simmer slowly for another 30 minutes until almost dry.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young green peas
- Form the main body of the dish and set its tender texture once cooked.
- Butter
- Adds richness and a smooth, silky mouthfeel to the finished peas.
- Flour
- Thickens the cooking liquid so the peas become less watery and cling together.
The step that matters
Simmering until almost dry. Simmering slowly for the final 30 minutes lets the liquid reduce and thicken around the peas. Stopping at the right point keeps them moist without a watery finish, and prevents scorching on the base of the pan.
Swap the peas
How well each one fits the dish's main ingredients (parsley, sugar, butter, flour):
- Almondfits better
- Chestnutfits better
- Chickpeafits better
- Peasthe original
Fit is the average pairing score against parsley, sugar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
