Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Add bulk and savory, earthy flavor while softening into the sauce.
- Cucumbers
- Add moisture and a mild, fresh texture that softens as it cooks.
- Butter
- Carries the curry powder's aroma and adds richness to the sauce.
- Onion
- Adds sweetness and body as it softens into the sauce.
- Curry powder
- Provides the warm, spiced aroma that defines the dish.
The step that matters
Cook for 2 hours, stirring occasionally. Long, gentle cooking lets the cucumber and mushroom release and lose water, so the sauce thickens. Stirring prevents scorching on the base of the pan as the liquid reduces.
