Why it works: Onion and spinach match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,336 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Prawn Curry
Ingredients
Directions
Make the curry
In a stewpan, melt the butter over medium heat.
Add the chopped onion and curry powder; sauté until the onion is soft.
Stir in the prawns and cook for a few minutes.
Add the spinach and finish
In a separate saucepan, cook the spinach without water until wilted.
Press the liquid from the spinach and add it to the stewpan.
Stir well, adding a little water if necessary to prevent burning.
Let the mixture stew for a few minutes to combine the flavors.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Prawns
- Provide the main protein and body of the curry, becoming firm and opaque when cooked.
- Butter
- Carries the curry powder's fat-soluble flavor compounds and adds richness to the sauce.
- Onion
- Softens and sweetens as it cooks, forming the flavor base for the curry.
- Curry powder
- Supplies the spice aroma and flavor that defines the dish, bloomed in hot fat.
- Spinach
- Adds moisture, mild earthy flavor and soft texture once wilted and pressed.
The step that matters
Stirring in water to prevent burning. Curry powder and onion can scorch on direct heat in the stewpan, and the spices turn bitter when burnt. Adding a little water and stirring steadily keeps the mixture moving and the spices tasting fresh.
