What each ingredient does
- Round steak
- Provides the main protein; slow stewing breaks down its connective tissue so it becomes tender.
- Onions
- Add sweetness and aroma as they soften and release flavour into the stewing liquid.
The step that matters
Stew slowly for three hours or more. Round steak is a lean, tough cut. Gentle, prolonged moist heat converts its collagen to gelatin, so stopping early leaves the meat chewy. Keeping the heat low and gentle in a double boiler prevents the meat from toughening through hard boiling.
