How do you get crispy duck skin?
Score the skin in a crosshatch pattern before roasting, then roast skin-side up. The scored surface allows fat to render while air circulation crisps the exterior.
Can you substitute one large duck instead of two?
Yes, use one 10–12 lb duck and reduce the glaze proportionally by half. Roasting time remains similar, around 1.5–2 hours depending on size.
How do you know when the duck is done?
Roast until a meat thermometer inserted into the thickest thigh reaches 165°F and the thigh meat is no longer pink.
What can replace harissa paste?
Use sriracha, chili garlic paste, or a blend of paprika and cayenne pepper (1 tbsp paprika + 1/4 tsp cayenne as a base).
How should leftover roast duck be stored?
Refrigerate carved duck and vegetables in an airtight container for up to 3 days; reheat gently in a 325°F oven to avoid drying out the meat.
