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 ↓
Stewed Rump of Beef with Onions
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Cut the rump of beef into large pieces.
Brown and simmer
Melt the butter in a pot over medium heat.
Add the beef and brown on all sides.
Slice the onions and add them to the pot.
Pour in the beef broth and season with salt and pepper.
Cover and simmer for 2 hours until the beef is tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump of beef
- Provides the meat that becomes tender during long, slow simmering.
- Onions
- Add sweetness and aroma as they soften in the pot.
- Butter
- Adds fat for browning the beef and carries flavour in the pot.
- Beef broth
- Supplies liquid that cooks the beef gently and forms the base of the sauce.
The step that matters
Browning the beef on all sides. Browning creates savoury flavour through the Maillard reaction. Crowding the pot or skipping the sear leaves the beef grey and the stew flat-tasting.
