Why it works: Butter and mushroom are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the bulk of the stew, softening into tender pieces during the long simmer.
- Flour
- Coats the slices so they brown in the butter and help thicken the gravy.
- Butter
- Fat for frying that gives the slices a golden, browned surface and rich flavour.
- Gravy
- Provides the liquid base in which the cucumbers stew and absorb savoury flavour.
The step that matters
Frying the floured slices until golden. Flour browns quickly in hot butter, so the heat must be controlled. Too hot and the coating scorches before the slices are cooked through, leaving a bitter taste.
