Ingredients
Directions
Prepare the beef
If using raw beef, hang it until tender.

Make the gravy

Add port wine and shalot vinegar.
Warm the mixture.
Strain the gravy through a fine sieve to remove herbs and vegetables.
Return the gravy to the saucepan with the beef.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main meat, which becomes tender through long, gentle simmering.
- Port wine
- Adds sweetness and depth of flavour to the gravy.
- Shalot vinegar
- Adds acidity that brightens the rich gravy.
- Butter
- Enriches the gravy and, kneaded with flour, thickens it.
- Flour
- Thickens the gravy as it cooks with butter, giving it body.
- Brown sugar
- Adds sweetness and helps round out the gravy's flavour.
The step that matters
Heat through without boiling. Once the sliced beef goes into the thickened gravy, boiling can toughen the meat and cause the gravy to break or separate. Gentle heat keeps the beef tender and the sauce smooth.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beef, meat, pepper, port wine, vinegar, butter, flour):
- Shallotfits better
- Capsicumfits better
- Mustardfits about as well
- Onionthe original
Fit is the average pairing score against beef, meat, pepper, port wine, vinegar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
