Why it works: Butter and mushroom are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Hamburg Steaks
Ingredients
Directions
Prepare the patties
In a bowl, combine minced meat, onion juice, coarse sea salt, and pepper.
Mix well and form into round, flat cakes.
Cook and make the gravy
Heat butter in a frying pan over medium‑high heat.
Add the steaks and cook until browned on both sides.
Transfer the steaks to a hot platter.
In the same pan, add flour to the remaining butter and mix thoroughly.
Gradually add boiling water, stirring until smooth.
Season with salt, pepper, and optional sauce, then pour over the steaks and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Minced beef steak
- Forms the body of the patties and gives them their meaty flavour and chew.
- Butter
- Fat that browns the patties and enriches the pan gravy.
- Flour
- Thickens the pan juices into a smooth gravy as it cooks in the fat.
- Onion juice
- Adds savoury onion aroma and flavour to the meat.
The step that matters
Adding the boiling water to the flour and butter. Pouring the water in gradually while stirring keeps the flour smoothly dispersed, so the gravy thickens without lumps.
Swap the onion
How well each one fits the dish's main ingredients (pepper, butter, flour, mushroom):
- Shallotfits better
- Spinachfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against pepper, butter, flour, mushroom. Candidates are from the same food group and used in at least 100 recipes.
