Why it works: Beans and flour are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,080 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Wax Beans
Ingredients
Directions
Prepare
Break off the ends of the wax beans and snap them into 1-inch pieces.
Wash the beans and drop them into boiling water.
Cook
Cook until tender, about 2 to 2.5 hours for market beans, less for freshly gathered ones.
In a separate bowl, mix cream with flour until smooth.
When beans are nearly done, add the cream mixture and let it come to a boil.
Serve
Serve warm, not hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wax beans
- Provide the main vegetable body and tender texture when cooked through.
- Cream
- Adds richness and a smooth, creamy coating to the beans.
- Flour
- Thickens the cream mixture so it clings to the beans instead of thinning out.
The step that matters
Adding the cream mixture. Flour in cream can clump or scorch if added to a hot pot without being smoothed first. Mixing it until smooth and adding it when the beans are nearly done lets it thicken evenly and cook through without curdling or sticking.
Swap the beans
How well each one fits the dish's main ingredients (cream, flour):
- Almondfits better
- Pistachiofits better
- Cashew nutfits better
- Beansthe original
Fit is the average pairing score against cream, flour. Candidates are from the same food group and used in at least 100 recipes.
