Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the main bulk and moisture, softening into a tender, mild-flavoured curry as they simmer.
- Mushrooms
- Add savoury depth and a meaty texture that holds up to long simmering.
- Curry powder
- Supplies the warm spice aroma and flavour that defines the dish.
- Onion
- Softens and sweetens as it cooks, forming the flavour base of the curry.
- Butter
- Carries fat-soluble flavour from the spices and gives the base a rich mouthfeel.
The step that matters
Simmer for 2 hours. Cucumbers contain a lot of water and soft cell walls, so long cooking can turn them mushy and dilute the sauce. Keep the heat low and check the texture as it cooks.
