Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture and set into a firm, sliceable custard around the rice.
- Half and half (cream and milk)
- Adds moisture and richness, helping the bake stay tender rather than dry.
- Cooked rice
- Forms the bulk of the dish, giving body and structure once the egg sets.
- Cheddar cheese
- Adds fat and savory flavor, and melts to bind the bake together.
The step that matters
Do not overcook. Egg proteins set as they heat, and past the point of firmness they tighten and squeeze out liquid, leaving the bake dry and grainy. Pulling it once the centre is just firm lets residual heat finish the set.

Fit is the average pairing score against egg, cream, milk, rice, onion, pepper, cheddar cheese. Candidates are from the same food group and used in at least 100 recipes.
