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 ↓
Braised Beef
Ingredients
Directions
Brown the meat
Fry the pork until crispy.
Add sliced onion and fry until golden brown.
Remove the onion from the pan.
Cut the steak into 1.5‑inch squares and brown on all sides.

Braise
Pour boiling water over the meat to cover and cook slowly for about 3 hours until tender.
Add more water if it boils away too quickly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Becomes tender during long, slow cooking in liquid as its connective tissue breaks down.
- Flour
- Coats the browned meat and thickens the cooking liquid into a gravy.
- Fat pork
- Renders fat into the pan that browns the meat and adds savory flavor.
- Onion
- Browns in the rendered fat, adding sweetness and aroma to the braising liquid.
The step that matters
Keep the meat covered and simmering slowly. If the water boils away and the meat is exposed, it dries and toughens. Slow, gentle simmering lets tough collagen convert to gelatin, so the beef turns tender rather than stringy.
Swap the onion
How well each one fits the dish's main ingredients (pork, pepper, flour):
- Capsicumfits better
- Potatofits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against pork, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
