Bake the potatoes for 1 hour at 350 degrees until tender. Cut in half length wise and scoop out the potato. Leave a ½ inch border. Brush the potato halves with oil and bake again at 400 degrees for 15 minutes until gold and crispy. Remove them and place a dollop of Crema Mexicana inside each one. Add the crumbled bacon, sliced scallions, and crumbled Queso Fresco on top.
