Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Softens and sweetens as it fries, building the base flavour of the dish.
- Shrimp
- Provides the main protein and seafood flavour, cooked through by brief heating.
- Boiled rice
- Forms the bulk of the dish, absorbing flavour from the onion and fat.
- Parmesan cheese
- Adds savoury, salty flavour and a little richness that clings to the rice.
The step that matters
Add the boiled rice and Parmesan cheese, stirring well.. The rice must be very dry so it fries and separates rather than turning mushy. Stirring well spreads the cheese evenly and coats each grain, so the dish does not clump.
Swap the mustard
