Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Hamburg Steak
Ingredients
Directions
Prepare the meat
Cut off the tough end of the steak and chop it finely.
Mix the chopped steak with pepper, salt, and onion juice.
Moisten your hands with cold water to prevent sticking.
Form the mixture into round cakes or steaks, using about 2 tablespoons of meat for each.
Cook and serve
Fry the cakes in butter until nicely browned on both sides.
Serve on a hot platter with melted butter poured over.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sirloin steak
- Provides the meat that forms the body and bite of the patties.
- Butter
- Conducts heat for frying and promotes browning on the surface of the cakes.
- Onion juice
- Adds savory onion flavor to the raw meat mixture.
The step that matters
Frying the cakes in butter until nicely browned on both sides. Browning comes from surface heat triggering Maillard reactions, which build flavor. Frying too gently or too briefly leaves the cakes grey and bland, while the interior still needs enough heat to cook through.
Swap the onion
How well each one fits the dish's main ingredients (pepper, butter):
- Capsicumfits better
- Potatofits better
- Carrotfits about as well
- Onionthe original
Fit is the average pairing score against pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
