What each ingredient does
- Duck
- Forms the main body of the stew and releases fat and flavour as it cooks.
- Giblets
- Simmered in the stock to build a rich, savoury base for the gravy.
- Stock
- Provides the liquid that becomes the gravy and carries the other flavours.
- Onion
- Adds aromatic sweetness and body to the gravy as it simmers.
- Lemon juice
- Adds acidity that brightens the rich gravy and balances its fattiness.
