What each ingredient does
- Sirloin or round steak
- Forms the wrapper that holds the filling and becomes tender during slow simmering.
- Bacon
- Adds fat and smoky flavor that carries into the filling and the pan.
- Flour
- Coats the rolls to help them brown and later thickens the cooking liquid into gravy.
- Bacon drippings
- Fat for frying that promotes browning on the outside of the rolls.
The step that matters
Frying the rolls until brown. Browning the flour-coated surface creates flavor through the Maillard reaction. Frying too little leaves the rolls pale and bland before the long simmer.
