Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Carries the curry powder's aroma and gives the sauce richness.
- Curry powder
- Provides the spiced aroma that defines the dish.
- Cucumbers
- Release water as they cook, giving the sauce moisture and a soft texture.
- Onion
- Softens and turns sweet as it cooks, adding body to the sauce.
- Minced mushrooms
- Add savoury depth and some body to the sauce.
The step that matters
The long, occasionally stirred cook. Cucumbers are mostly water and break down over a long cook, so the dish can turn mushy. Stirring occasionally keeps the solids from sticking and scorching on the base of the pan during the two hours.
