Ingredients
Directions
Make the stock
Boil the onion in a small amount of water until it becomes a pulp.
Add the heads and shells of the prawns to the onion pulp and strain the mixture.
Pour the strained liquid into a stewpan and warm it gently until it simmers.
Cook the curry
Add the prawns, curry powder, and Cornubian sauce to the stewpan.
Let the mixture simmer for about 2 minutes, stirring well.
Serve
Serve the prawns over boiled rice.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Onion and sauce barely smell alike, yet cooks put them together in 10,474 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Softens into a pulp that thickens the liquid and adds body and mild sweetness.
- Prawns
- Provide the main protein, and their shells add savoury flavour to the strained liquid.
- Curry powder
- Supplies the warm spice aroma and the characteristic flavour of the dish.
The step that matters
Simmering the prawns. Prawn protein tightens and turns rubbery when overheated for too long, so the prawns should be simmered only briefly, just until cooked through.
Swap the onion
How well each one fits the dish's main ingredients (sauce, rice):
- Tomatofits better
- Welsh onionfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against sauce, rice. Candidates are from the same food group and used in at least 100 recipes.
