I love this pancake! Good apples to use would be Granny Smith, Jonagold or McIntosh. If you have access to heirloom apples, choose some that have some tartness to them. This recipe is adapted from "The Pancake Handbook".
Melt remaining 4 T of the butter in an oven-proof 10-inch skillet (a well-seasoned cast iron skillet is good) until just beginning to brown, about 2 minutes; spread apples in bottom of pan, pour batter over apples.
06Bake until the pancake is golden brown and puffed, about 20 minutes; invert onto a large platter.
07Sprinkle with remaining lemon juice; dust with confectioners' sugar.
