Roast Duck with Apples

Oven, in the book's wordsA hot oven

Ingredients

1 duck
12 small sour apples
Coarse sea salt
Black pepper

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

Pluck and singe the duck, then draw it without breaking the intestines.
Wipe the duck with a wet towel and place it in a baking pan.
Wipe the apples with a wet cloth, core them without breaking, and arrange them around the duck.

Roast and serve

Place the pan in a 400°F (200°C) oven to quickly brown the duck.
Reduce the oven temperature to 350°F (175°C) and cook for about 20 minutes, or until the apples are tender but not broken.
Baste the duck and apples every five minutes until done, then serve on the same dish.

What each ingredient does

Duck: Provides the main meat and rendered fat that browns and flavours the dish.
Sour apples: Soften during roasting and absorb the fat and juices from the duck, adding tartness.

The step that matters

Reduce the oven temperature to 350°F (175°C). Roasting at the high initial heat browns the skin quickly, but lowering the heat lets the duck cook through without burning the outside. Checking the apples at this stage keeps them tender rather than broken.
