Preheat the oven to 425 degrees F. Line a baking sheet with parchment.
Fry the bacon in a nonstick skillet until cooked but not yet crisp. Remove the bacon to a paper towel lined sheet tray. Let cool. Reserve the bacon drippings in the skillet.
Whisk together the flour, sugar, baking powder, and salt in a medium bowl. Add the cheese and bacon and toss. Stir in 1 1/2 cups of cream with a wooden spoon until the dough comes together. Remove the dough to the countertop and knead briefly until it is smooth and uniform in appearance. Pat the dough out to a 1-inch thickness. Using a biscuit cutter dipped in flour, punch out dough rounds. Push together the leftover dough and pat out again to 1-inch thick and cut out rounds. Arrange the biscuits on the parchment lined sheet tray.
In a small bowl, whisk together the remaining 1 tablespoon of cream and the egg. Brush the tops of the biscuits with the egg wash and sprinkle with kosher salt. Put immediately into the oven and bake for 18 minutes.
When the biscuits come out of the oven, start frying the eggs. Heat the same nonstick skillet used earlier (to cook the bacon) over medium heat. Once heated, crack the eggs into the pan and cook until the white is set and the eggs begin to turn golden brown. Spoon some of the hot grease over the yolks to help it cook. Season with salt and pepper, to taste.
To assemble the sandwiches, split the biscuits in half and spread some mango preserves on the inside of the biscuit tops. Put a small handful of arugula on each of the bottoms. Top with the fried eggs and cover with the top of the biscuit. Serve immediately.
