Why it works: Pork and onion are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,214 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beefsteak Smothered in Onions
Ingredients
Directions
Brown the base
Fry the salt pork in a skillet until brown, then remove it from the pan.
Add the sliced onions to the skillet and fry for about 10 minutes, stirring constantly.
Layer and cook
Layer the steak on top of the onions, then add another layer of onions, followed by another slice of steak.
Cover the top with a thick layer of onions and dredge each layer with pepper, salt, and flour.
Pour the boiling water over the layers and cover tightly.
Simmer for half an hour.
Serve
When serving, place the steak in the center of the dish and heap the onions around it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Main protein; slow simmering under a lid makes it tender.
- Onions
- Cook down to sweetness and, with the water, form a moist braising bed.
- Salt pork
- Renders fat and browns in the pan, flavouring the onions and frying fat.
- Flour
- Dusted on each layer, it helps thicken the cooking juices into a gravy.
- Boiling water
- Creates steam and liquid that braises the steak and onions.
The step that matters
Pour the boiling water over the layers and cover tightly.. A tight lid traps steam so the steak braises in moisture instead of drying out. Gentle simmering then breaks down connective tissue slowly, keeping the meat tender.

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