Make Apple Popovers
In a medium bowl, whisk together flour and salt. In a blender combine milk, eggs and 5 tbsp melted butter. Blend on medium-high speed 20 seconds. Whisk into flour mixture until just combined. Let stand at room temperature 30 min.
Meanwhile, heat oven to 450°F and place rack in lower third. Cut remaining 2 tbsp butter into 12 pieces and divide among cups of a 12-cup popover pan. Place 1 tbsp apple into each cup. Just before baking, transfer pan to oven and heat until butter is melted and pan is hot, about 1 min.
Carefully remove pan from oven and evenly pour batter over apples. Immediately return pan to oven. Bake 15 min (do not open oven). Reduce oven to 375°F and bake until popovers are crisp and browned, 18 to 20 min more.
Turn out popovers onto a wire rack and let cool 2 to 3 min. Serve hot with Maple Spiced Butter
