For this recipe to be truly authentic you need real French
'magrets de canard', which are the breasts of ducks that have been fattened to
produce foie gras, and the fresh red cherries from Roussillon in the south of
France.
But this recipe is a compromise, allowing for the difficulty of obtaining those specific ingredients.
Duckling à la Montmorency, as it is sometimes called, is a classic of French cuisine.
You can make the sauce with both sweet and tart cherry varieties, or both fresh and canned fruit. Fresh are obviously better, but canned pitted cherries are more convenient, but be sure to use canned fruit, not the thick pie filling that also comes in cans. Adjust the sugar to taste.
The key to success is getting the cooking of the duck breasts exactly as you like them.
Since they come in different sizes, and, sometimes, of varying quality, this takes a bit of practice and experimentation in your own kitchen.
But keep notes of what you do at each stage, and vary this
recipe accordingly so that you get perfect duck breasts every time.
