Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump of beef
- Is the main cut that becomes tender and flavorful during the long marinade and roast.
- White wine
- Acidity in the marinade helps tenderize the meat and adds bright flavor.
- Oil
- Carries fat-soluble flavors through the marinade and helps the surface brown.
- Shredded onions
- Release moisture and savory flavor into the marinade and the gravy.
The step that matters
Basting and adding marinade to the gravy. Basting keeps the surface moist and encourages even browning, while adding marinade to the drippings builds flavor. Adding it too early can scorch sugars or dilute the gravy, so timing matters.
