This is a planning estimate, not a doneness test. Oven calibration, bird shape, and stuffing density all shift real cooking time by twenty minutes or more in either direction.
How the numbers work
Each oven-temperature preset uses a minutes-per-kilogram band drawn from common roasting practice: lower heat renders more fat and gives a wider, more forgiving window; higher heat crisps skin faster but narrows the margin for error. The planner multiplies that band by your bird's weight, then nudges it upward if the duck is stuffed or going in cold from the fridge — both slow how quickly heat reaches the centre.
The suggested prep-start time works backward from your target serving time, adding the top of the cooking range, a 20-minute rest, and a margin for carving and plating. Real ovens vary, so treat the first check-in point as the start of a window, not the finish line.
Common questions
- Why is the result a range instead of one number?
- Oven calibration, bird shape, and how tightly it's trussed all shift real cooking time. A range keeps expectations honest instead of implying false precision.
- Does the planner replace a thermometer?
- No. It only tells you roughly when to start checking. Doneness is always confirmed with a food thermometer, not a clock.
- Why do stuffed and fridge-cold birds take longer?
- Stuffing slows heat reaching the cavity, and a cold start means more of the cook goes into raising the bird's core temperature before it can brown.
