Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Releases juices and gelatin as it simmers, giving the gravy body and savory depth.
- Onions
- Stew down and brown slowly, adding sweetness and color to the gravy.
- Fat
- Carries heat into the pot and helps the onions and meat brown rather than steam.
- Cold water
- Forms the liquid base that extracts flavor from the beef and onions during simmering.
The step that matters
Browning the onions without burning them. Slow, moderate heat lets sugars in the onions caramelize into brown flavor. Too much heat scorches them, leaving bitter notes that carry into the finished gravy.
Swap the onion
How well each one fits the dish's main ingredients (butter, beef, pepper):

- Capsicumfits about as well
- Tomatofits about as well
Fit is the average pairing score against butter, beef, pepper. Candidates are from the same food group and used in at least 100 recipes.
