Roast Duck
Ingredients
Directions
Prepare the duck
Singe the duck and draw it.
Cut off the wing bones at the first joint and the toes.
Scald and skin the feet, then fold them onto the back of the bird.
Fill the body with sage and onion stuffing and fasten with skewers.
Make a small slit in the skin at the apron and catch the tip of the tail.
Truss the bird with needle and string, securing the skin at the tail.
Roast and serve
Place the duck in a tin with 2 oz of hot dripping.
Roast for 1 to 2.5 hours, basting frequently.
Serve with thickened gravy, garnished with watercress, and apple sauce on the side.

What each ingredient does
- Duck
- Provides the main meat, whose fat renders during roasting to crisp the skin.
- Sage and onion stuffing
- Fills the body, adding moisture and aroma to the meat as it cooks.
- Hot dripping
- Conducts heat into the skin and promotes even browning while basting.
