Ingredients
Directions
Prepare the beef
Cut the beef into delicate slices, discarding tough parts and skin.
Make the sauce
In a saucepan, combine the gravy from the previous day with water, catsup, herbs, onion, salt, and cayenne.
Stew for 15 minutes.
Take out 1 cup of the liquid and mix it with flour until smooth.
Stir the flour mixture back into the saucepan and cook for 10 minutes.
Strain the mixture, return it to the pan, and add the beef slices.
Heat gently without boiling.
Finish and serve
Before serving, stir in the tarragon vinegar and arrange toasted bread snippets around the dish.

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 and body of the hash, gently warmed through in the sauce.
- Flour
- Thickens the liquid into a smooth sauce when cooked, giving the hash body.
- Tarragon vinegar
- Adds acidity that brightens the rich, savory sauce just before serving.
- Catsup
- Adds sweetness and tomato acidity that deepens the color and flavor of the sauce.
- Onion
- Contributes savory aroma and sweetness as it cooks into the sauce.
The step that matters
Heat gently without boiling. Boiling toughens the thin beef slices and can break up the flour-thickened sauce, so keep it at a gentle heat once the beef is added.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper, flour, tarragon, vinegar, bread):
- Shallotfits better
- Mustardfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against beef, pepper, flour, tarragon, vinegar, bread. Candidates are from the same food group and used in at least 100 recipes.
