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 water for 15 minutes, then dry and fry until brown.
Make the sauce
Pour off the fat and add boiling water.
Mix in butter rolled in flour, ketchup, mushroom pickle, white wine, and the onion.
Stir for a few minutes, then add the beans and shake the pan to mix well.
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 and carry the sauce.
- Butter
- Adds richness and body to the sauce, with flour helping it thicken.
- White wine
- Adds acidity and depth of flavour to the sauce.
- Ketchup
- Adds sweetness and tang to the sauce.
- Mushroom pickle
- Adds savoury, umami-rich flavour to the sauce.
The step that matters
Frying the beans until brown. Drying the beans well before frying lets their surface brown rather than steam. Browning builds savoury flavour through the Maillard reaction, and wet beans would stay pale and soft.
Swap the mace
How well each one fits the dish's main ingredients (beans, butter, ketchup, mushroom, white wine, onion, clove):
- Thymefits better
