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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the meat that becomes tender during the long cooking after marinating.
- Vinegar
- Acidity that softens the meat fibres during marinating and gives the dish its sour flavour.
- Flour or ginger snaps
- Thickens the strained broth into a gravy.
The step that matters
Allow to marinate for a week in winter or 3-4 days in summer, turning daily and keeping covered.. The acid in the vinegar slowly softens tough connective tissue in the meat and flavours it throughout. Turning keeps every surface in contact with the liquid, and covering keeps the marinade from drying out or spoiling, so the timing matters.
