Ingredients
Directions
Prepare the beef

Cut the beef into thin slices.
Simmer and strain
In a stewpan, add the beef, water to cover, sweet herbs, onion, pepper, and salt.
Cover and simmer until tender.
Add port wine and eschalot vinegar, then warm through.

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; long hanging and simmering make it tender.
- Port wine
- Adds sweetness and depth of flavour to the sauce.
- Eschalot vinegar
- Adds acidity that sharpens the flavour of the sauce.
- Flour
- Thickens the sauce so it clings to the beef.
- Butter
- Adds richness and, kneaded with flour, helps thicken the sauce.
- Brown sugar
- Adds sweetness and helps round out the sauce's flavour.
The step that matters
Heating the sliced beef without boiling. Once the sliced beef is added, boiling the sauce can toughen the meat and make it dry. Keeping it just below a boil heats it through while it stays tender and moist.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beef, pepper, port wine, vinegar, butter, flour, sugar):
- Capsicumfits better
- Shallotfits better
- Mustardfits about as well
- Onionthe original
Fit is the average pairing score against beef, pepper, port wine, vinegar, butter, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
