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 ↓
Stewed Green Peas
Ingredients
Directions
Cook the peas
Boil the peas in a saucepan of boiling water until very tender.
Drain the peas in a colander.
Finish the stew
Melt the butter in a small pan, then stir in the flour until well combined.
Add the butter‑flour mixture to the peas and boil for an additional 8 minutes.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the main body of the dish and provide its tender, starchy texture once boiled.
- Butter
- Adds richness and a smooth mouthfeel to the stew.
- Flour
- Thickens the cooking liquid so the peas are coated in a stewed sauce.
The step that matters
Stirring the flour into the butter before adding it to the peas. Cooking flour in melted butter, stirred until fully combined, prevents raw starch and lumps, so the liquid thickens evenly rather than clumping when added to the hot peas.
Swap the peas
How well each one fits the dish's main ingredients (butter, flour):
- Almondfits better
- Macadamia nutfits better
- Cashew nutfits better
- Peasthe original
Fit is the average pairing score against butter, flour. Candidates are from the same food group and used in at least 100 recipes.
