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

What each ingredient does

Green peas
Add sweetness, color, and a tender texture to the finished dish.
Rice
Forms the bulk of the dish and gives it a fluffy, separate-grain texture.
Onions
Browning in butter builds sweet, savory flavor that seasons the rice and peas.
Butter
Carries the onion frying and adds richness and flavor.

The step that matters

Fry the onions until lightly browned. Onions cook down slowly in fat, and browning them develops sweet, savory flavor. Burning them makes the dish bitter, while undercooked onions taste raw.

Swap the peas

How well each one fits the dish's main ingredients (rice, onion, parsley, butter, pepper):
