In a small bowl, soak the white bread in the heavy cream for 5-10 minutes. Mash with a spoon or your hands. Mix the bread paste in a large bowl with the garlic and onion powder, beef and pork, egg, brown sugar, salt, and pepper. When it’s all well-mixed, roll into smallish meatballs.
Preheat the oven to 400 degrees. Place meatballs on a sheet pan or baking dish. Bake for 20-25 minutes until cooked through.
In a large pan, melt the butter over medium heat. Whisk in the flour; let it bubble for 2-3 minutes. Add the beef broth, slowly, stirring after each addition. Gradually a smooth gravy should start to form. Stir in the heavy cream and season with Worcestershire sauce, sugar, salt, and a bit of nutmeg if you want. Taste and adjust to get it just right!
Add meatballs in with the gravy. Cover to keep warm until you want to serve them, or transfer the pan to the oven where they can hang out on low / warm heat and continue to get tender and delicious.
