Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef (top of the round)
- Provides the meat that forms the patty's main structure and rich, beefy flavor.
- Bread crumbs
- Absorb juices and moisture, helping the patty stay tender rather than dry.
- Egg
- Binds the mixture together so the patties hold their shape during cooking.
- Onion
- Adds moisture and savory sweetness that mellows as it cooks inside the patty.
The step that matters
Cook the patties in a skillet over medium heat until browned and cooked through. Medium heat lets the surface brown through the Maillard reaction while the interior cooks evenly. Too high a heat can scorch the outside before the center is safely cooked, while a patty that is not cooked through may be unsafe to eat.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beef, pepper, bread, egg):
- Capsicumfits better
- Tomatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against beef, pepper, bread, egg. Candidates are from the same food group and used in at least 100 recipes.
