Place the apple mixture in a baking dish and cover with aluminum foil after everything has been combined. The apples should be soft & aromatic after 30 to 40 minutes of baksbteing at 350°F (175°C) in a preheated oven. Remove the foil during the final ten minutes of baking to give the top a little caramelization, which will add a lovely texture contrast. Rummy apples are praised for their decadent flavor, but when consumed in moderation, they also have a number of health advantages that make them a guilt-free treat.
