Method:

1. Season the duck breast with the spiced salt and sugar for 1 hour then remove the cure.
2. Place the duck breast skin-side down in a pan and slowly caramelise. Turn over and continue to cook. When medium-rare remove from the pan and rest.

Sauce

1. Cook sugar in a dry 1-quart heavy saucepan over moderate heat, undisturbed, until it begins to melt. Continue to cook, stirring occasionally with a fork, until sugar melts into a deep golden caramel. Add orange juice, vinegar, and salt (use caution; mixture will bubble and steam vigorously) and simmer over low heat, stirring occasionally, until caramel is dissolved. Remove syrup from heat.
2. Add enough stock to the pan that you cooked the duck breast in to total 1 cup liquid.
3. Stir butter and flour together to form a beurre manié. Bring pan juices to a simmer in a 1- to 2-quart heavy saucepan, then add beurre manié, whisking constantly to prevent lumps. Add orange syrup and zest and simmer, whisking occasionally, until sauce is thickened slightly and zest is tender which should be about 5 minutes.
4. Serve with duck.
