Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Upper round beef
- Forms the main body of the roast, becoming tender as it cooks slowly in liquid.
- Tomatoes
- Add acidity and moisture, building the sauce that flavours the gravy.
- Onions
- Break down during long cooking, adding sweetness and body to the gravy.
- Grated cheese
- Melts over the top, adding richness and savoury flavour to the finished dish.
- Dripping
- Provides fat for searing, which browns the meat surface and deepens flavour.
The step that matters
Searing the meat in hot fat on all sides. Dry, hot searing browns the surface through the Maillard reaction, building flavour that carries into the gravy. Meat that is crowded, wet, or not hot enough will steam and turn grey instead of browning.
Swap the onion
How well each one fits the dish's main ingredients (beef, tomato, cheese, pepper, flour):
- Capsicumfits better
