Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hot cooked brown rice
- Forms the bulk of the dish and absorbs flavor from the beef broth it was cooked in.
- Vegetable oil
- Conducts heat to soften the vegetables and keeps them from sticking to the pan.
- Green pepper
- Keeps a crisp bite and adds mild, fresh sweetness when cooked only briefly.
- Green onions
- Adds a sharp, fresh aroma that mellows as it cooks in the oil.
The step that matters
Cook onions and green pepper until tender crisp. Vegetables keep their bright color and slight bite when heated briefly. Cooking them too long softens their cell structure, so they turn limp and dull in color before the rice is added.
Swap the onion
How well each one fits the dish's main ingredients (pepper, rice, beef, cheese):
- Tomatofits better
- Capsicumfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against pepper, rice, beef, cheese. Candidates are from the same food group and used in at least 100 recipes.
