Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Steak with Onions
Ingredients
Directions
Sear the steak
Heat a frying pan until very hot and grease it with hot lard.
Add the steak and crisp it quickly on both sides.
Remove the steak to a dish and keep warm.
Make the onion gravy
In the same pan, add the chopped onions and scald them with boiling water.
Season the onions with salt and pepper.
Fry the onions until light brown.
Add the butter and dredge the onions with flour.
Pour in enough milk or cream to create a nice gravy.
Bring the gravy to a boil.
Pour the gravy over the steak.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Porterhouse steak
- Provides the main meat, seared quickly to brown the outside while staying tender inside.
- Onions
- Soften and turn sweet as they fry, adding flavor to the gravy.
- Flour
- Thickens the pan juices and butter into a gravy that coats the steak.
- Milk or cream
- Adds moisture and richness, forming the body of the gravy.
The step that matters
Crisp the steak in very hot fat. A very hot pan with hot lard browns the surface quickly, building flavor through browning before the inside overcooks. A cool pan would steam the meat and leave it grey.
Swap the onion
How well each one fits the dish's main ingredients (pepper, butter, flour, milk):
- Potatofits better
- Capsicumfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against pepper, butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
