Why it works: Mushroom and white wine are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,765 recipes. Both carry ethyl octanoate, which smells fruity. The science ↓
French Beans
Ingredients
Directions
Prepare the beans
Cut and string the beans, then cut them into three pieces.
Soak the beans in salt and water for 30 minutes, then dry them.
Fry the beans until brown, then pour off the fat.
Make the sauce
Add boiling water and the butter rolled in flour to the pan.
Stir in ketchup, mushroom pickle, white wine, onion, mace, nutmeg, pepper, and salt. Mix well and add the beans.
Shake the pan until combined.
Remove the onion and transfer the mixture to a serving dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- French beans
- Form the main body of the dish, cooked until browned for a savoury bite.
- Butter
- Adds richness and, rolled in flour, thickens the liquid into a smooth sauce.
- White wine
- Adds acidity and depth of flavour to the sauce.
- Ketchup
- Contributes sweetness, acidity and a tangy savoury flavour to the sauce.
- Mushroom pickle
- Adds concentrated savoury, tangy flavour to the sauce.
The step that matters
Fry the beans until brown. Browning develops flavour through the Maillard reaction, but overcooked beans turn bitter and dry. Pour off the fat so the beans do not stay greasy in the sauce.
Swap the mace
How well each one fits the dish's main ingredients (beans, butter, ketchup, mushroom, white wine, onion, clove):
- Thymefits better
- Garlicfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against beans, butter, ketchup, mushroom, white wine, onion, clove. Candidates are from the same food group and used in at least 100 recipes.
