Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump of beef
- Forms the main cut; larding with fat keeps the lean meat moister during roasting.
- Onions
- Release moisture and sweetness into the marinade, adding flavour to the meat and gravy.
- Chablis (white wine)
- Acidity in the marinade helps tenderise the surface of the meat and adds aroma.
- Oil
- Carries fat-soluble flavour into the meat and helps the surface brown during roasting.
The step that matters
Adding marinade to the gravy when half roasted. Marinade added too early can burn or over-sweeten the drippings, while adding it at mid-roast lets it reduce gently into the gravy. Frequent basting keeps the surface moist so it browns evenly instead of drying out.
Swap the onion
How well each one fits the dish's main ingredients (beef, white wine, thyme, parsley, pepper):
