Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw beef
- Provides the protein structure that sets and holds the patty shape when cooked.
- Onion
- Adds moisture and aromatic sweetness to the meat as it cooks.
- Butter
- Adds fat and flavor, and helps the surface brown in the skillet.
- Lard
- Adds fat for frying, helping the balls brown evenly on the surface.
The step that matters
Fry the beef balls until browned on all sides. Browning comes from the Maillard reaction on dry, hot surfaces, so the balls need enough heat and room in the pan. Crowding the skillet or moving the balls too early traps moisture, steaming them grey instead of browning.
Swap the onion

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