How to Make It
In a large heavy skillet, boil the cider and Gewürztraminer, skimming occasionally, until reduced to 3 tablespoons, about 10 minutes; pour into a small bowl.
Wipe out the skillet, add 2 tablespoons of the butter and melt over high heat. Season the scallops with salt and pepper and cook until browned, about 2 minutes per side. Transfer the scallops to a warmed serving plate and cover loosely with foil.
Add the remaining butter to the skillet and melt over high heat. Add the cider mixture, apple, sage and lemon juice and cook until the apple is tender and the sauce is slightly thickened, about 3 minutes. Season with salt and pepper. Spoon the sauce over the scallops and serve.
