What each ingredient does
- Beef steak
- Provides the main protein, whose juices and fat carry the dish's flavour.
- Onions
- Browning in fat develops sweetness and deep savoury flavour that complements the steak.
- Beef drippings or butter
- Fat for frying that conducts heat to the onions and adds rich flavour.
The step that matters
Frying the onions until brown. Onions need enough heat and time for their sugars to caramelise; pale or steamed onions stay bland and soft, while properly browned ones taste sweet and savoury.
