Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Walnuts: Toast in butter to add nutty, browned flavor and crunch.
Butter or margarine: Carries the heat for browning the walnuts and adds richness.
Cooked rice: Forms the bulk of the dish and carries the other flavors.
Parmesan cheese: Adds savory, salty flavor and helps the rice cling together as it melts.

This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
