Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold roast beef
- Provides the main protein, which softens as it simmers in the sauce.
- Butter
- Adds fat and richness, and helps the diced beef brown lightly at the start.
- Tomato ketchup
- Adds sweetness and acidity, giving the stew its tangy, savoury flavour.
- Stock
- Supplies liquid so the beef stews gently and the sauce stays moist.
- Onion
- Adds sweetness and aroma as it softens in the simmering liquid.
The step that matters
Browning the diced beef. Stirring constantly until only lightly browned builds savoury flavour without drying or toughening the meat before the liquid is added.
