Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Forms the meat base of the cakes and provides their savory, browned flavor.
- Chopped onion
- Adds sweetness and aroma as it browns in the fat.
- Butter or drippings
- Conducts heat across the pan and adds fat that helps the meat brown.
The step that matters
Fry the meatballs until brown on both sides. Browning depends on a hot pan and a fairly dry surface. Crowding the pan or pressing the cakes traps moisture, so they steam and turn grey instead of browning.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper, butter):
- Potatofits about as well

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