Transfer apples and their juices to colander suspended over large mixing bowl to capture juices. The mixture should release at least ⅓ cup of liquid.
Place liquid and butter in small sauce pan.
Boil liquid, swirling but not stirring, until syrupy and lightly caramelized.
Allows liquid to cool approx 10 minutes or until warm.
Add almond extract or Kirsch.
Meanwhile, transfer apples to second large mixing bowl.
Toss apples with cornstarch until all traces of cornstarch have disappeared.
Pour syrup over apples, tossing gently. (If syrup hardens on contact with apples, it will dissolve during baking.)
