Preheat oven to 400 convection bake. Wash and cut the top and bottom of the apples. Use a paring knife and cut around the core in the center of the apple. Take your fingers and push the core out of the apple. If the core is too hard to remove, cut a little bit deeper around the core. For a swallow baking dish cut the apples in half around the middle of the apple. They should look like a barrel cut in half with 2 cut sides per apple. (I hope that’s not confusing. You want the hole in the apple facing up in the dish).
