Oysters with apple mignonette

Ingredients:

12 medium oysters, your choice of variety
1/2 cup apple cider
3 tablespoons finely chopped tart apple
2 tablespoons finely chopped red pepper
1 whole shallot, finely chopped
1 tablespoon finely chopped parsley
1 tablespoon cider vinegar
Coarsely ground black pepper

Methods:
Clean the oysters. Combine oysters and apple cider in a small saucepan and bring to a boil. Steam oysters, covered, over moderately high heat until they just open, about 4 minutes. Transfer to a plate after oysters have opened, reserve steaming liquid, and discard any unopened oysters. Chill oysters until cool, about 30 minutes.
While oysters are chilling, pour oyster steaming liquid through a paper towel-lined sieve into a bowl to remove any grit. Stir 2 tablespoons strained liquid together with remaining ingredients and salt to taste. Discard remaining strained liquid.
Remove flat half of oyster shell and loosen oyster with a sharp knife. Put oysters in rounded half of shell. Arrange on plates and spoon sauce over oysters.
