Ingredients
Directions
Prepare the filling
Mix the parsley, bread crumbs, egg, and seasoning in a bowl.
Cut the fat from the steak into small pieces and mix it with the bread mixture.
Shape the rolls
Cut the steak into squares about 2 inches wide and ½ inch thick.
Place a small amount of the mixture on each square and roll it up, tying with string.
Dip each roll in flour, then season with salt and pepper.
Brown and cook
Brown the rolls quickly in butter.
Place the rolls in a stewpan, add stock and sauces, and skim when boiling.
Cook slowly for 1.5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Forms the wrapper around the filling and becomes tender during slow cooking.
- Bread crumbs
- Absorbs moisture and binds the filling so it holds together inside the roll.
- Yolk of egg
- Acts as a binder that helps hold the bread crumb filling together.
- Flour
- Coats the rolls so they brown and help thicken the cooking liquid.
- Mushroom ketchup
- Adds savoury depth to the cooking liquid.
The step that matters
Brown the rolls quickly in butter. Searing creates browned flavour through the Maillard reaction. Browning quickly before simmering seals the surface and builds colour and taste without overcooking the meat.
Swap the parsley
How well each one fits the dish's main ingredients (bread, mushroom, ketchup, sauce, egg, flour, pepper):

Fit is the average pairing score against bread, mushroom, ketchup, sauce, egg, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
