Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beefsteak Smothebed in Onions
Ingredients
Directions
Prepare
Heat a little lard in a skillet.
Peel and slice the onions, then layer them over the steak until the skillet is full.
Season with salt and pepper.
Cook
Cover tightly and place over the fire.
Once the onion juice has boiled away and the meat starts to fry, remove the onions.
Turn the meat to brown the other side, then replace the onions.
Be careful not to let the onions burn.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef steak
- Is the main protein that browns and fries in the skillet.
- Onions
- Release their juice to steam the meat, then soften and sweeten as they cook.
- Lard
- Fat that conducts heat into the skillet and helps the steak brown.
The step that matters
Removing the onions at the right moment. Onions release juice that steams the meat first; once that juice has boiled away, the meat can fry and brown. Leaving the onions too long lets them burn, which adds bitter flavour to the pan and the dish.
