Roast duck — the slow-roasting technique that renders the duck's substantial fat layer without drying out the flesh — requires a different temperature and timing strategy from chicken roasting. The fat layer must render completely before the flesh is cooked; achieving both simultaneously requires a lower temperature for longer than seems necessary.
- **The fat rendering challenge:** A duck breast at 200°C cooks through before the fat layer renders — producing pink, perfectly cooked duck flesh surrounded by flabby, unrendered fat. The solution: start at a lower temperature (160°C) for 45–60 minutes to render the fat, then raise to 200°C for 15–20 minutes to crisp the skin. - **The scoring:** The fat cap scored in a diamond pattern (without cutting through to the flesh) — the cuts allow the fat to render from the interior of each diamond as well as the surface. - **The rack:** The duck roasted on a rack so that rendered fat drips away rather than pooling around the duck and producing steam. - **The cherry sauce:** A classic French accompaniment — reduced duck stock + fresh or frozen sour cherries + a small amount of red wine vinegar and sugar. The acid-sweet cherry sauce provides the contrast to the rich duck fat. - **The resting:** 20 minutes minimum — the fat layer retains heat and will continue cooking the flesh if carved immediately.
