What each ingredient does
- Spanish onions
- Provide the main body of the dish, softening into a tender, sweet base.
- Milk, butter, or cream
- Adds richness and moisture, turning the onions into a creamy sauce.
- Curry powder
- Supplies the spiced aroma and flavour that defines the dish.
The step that matters
Remove excess water. Water left in the chopped onions dilutes the dairy and curry powder, so the sauce stays thin and loose instead of clinging to the onions.
