1 1/2 tablespoons unsalted butter
1 Granny Smith apple, peeled, cored, and cut into 1/2 inch wedges
1/3 cup honey
1/4 teaspoon ground cardamom
3 large eggs
3/4 cup milk
3/4 cup all purpose flour
1/4 teaspoon salt
1 tablespoon confectioners' sugar
Heat oven to 400 degrees. Heat a well seasoned 10 inch cast iron skillet over high heat. Add butter. When melted, add apple wedges. Cook until softened and lightly golden, about 2 minutes. Stir in honey and cardamom, and remove skillet from heat.
In a separate bowl, whisk together remaining ingredients, except confectioners sugar, until smooth. Pour over apple mixture. Bake until puffed and brown, about 20 minutes.
Slide pancake onto a serving platter. Serve immediately, cut into wedges, with confectioners' sugar sifted over the top.
