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 ↓
Lima or Butter Beans
Ingredients
Directions
Prepare
Shell the beans and soak them in cold water for at least 1 hour.
Cook the beans
In a saucepan, bring enough boiling water to cover the beans and add a little salt.
Boil the beans steadily for 1 hour if young, or 1.5 hours if old.
Finish and serve
Drain most of the water, then rub 1 teaspoon of butter with 1 teaspoon of flour.
Simmer the mixture for 10 minutes, then add salt and black pepper to taste before serving.

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
- Lima or butter beans
- Provide the main body of the dish, becoming tender and creamy when boiled.
- Butter
- Adds richness and fat, giving the finished beans a smooth mouthfeel.
- Flour
- Thickens the cooking liquid when rubbed with butter and simmered.
The step that matters
Simmer the butter and flour mixture. Flour must be cooked for several minutes to lose its raw taste and to thicken properly. Simmering for the full 10 minutes lets the starch swell and the sauce become smooth rather than pasty or floury.
