Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lentils
- Provide the main body and protein-rich texture of the dish.
- Rice
- Adds bulk and a soft, starchy texture that absorbs the flavors of the pan.
- Butter
- Adds fat and richness, carrying flavor as it cooks the onion.
- Onion
- Browns in the butter to add sweetness and savory depth.
The step that matters
Drain the rice and let it dry. Leaving surface water on the cooked rice makes it gummy when it is fried; letting it dry at the oven door helps the grains stay separate in the pan.
Swap the lentils
How well each one fits the dish's main ingredients (rice, butter, onion, pepper):
- Black-eyed peafits better
- Sesamefits better
- Beansfits better
- Lentilsthe original
Fit is the average pairing score against rice, butter, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
