To Roast a Canvasback Duck

Oven, in the book's wordsA hot oven

Ingredients

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

  1. Pluck, singe, draw, and wipe the duck well. Do not wash it.

  2. Season the duck with coarse sea salt and cayenne pepper.

Roast

  1. Roast the duck in a 400°F (200°C) oven for 30 minutes, basting with butter and a little water.

  2. Transfer the duck to a hot platter.

Make the gravy and serve

  1. Add currant jelly and a dash of cayenne pepper to make gravy.

  2. Thicken the gravy with browned flour if desired.

  3. Serve immediately after roasting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Canvasback duck
Provides the main meat and the fat that renders during roasting.
Butter
Adds fat and richness, and helps the skin brown while basting.
Currant jelly
Adds sweetness and fruity acidity that balances the rich duck drippings in the gravy.
Browned flour
Thickens the gravy and adds a toasted, nutty flavour.

The step that matters

Serve immediately after roasting. Duck fat begins to set and the skin loses its crispness as it cools, so the bird is best carved and served while hot.

Swap the currant

How well each one fits the dish's main ingredients (pepper, butter, flour):
