Combine: ground beef, ground pork, crushed saltines, one egg, pepper, pinch of nutmeg. Form into meatballs. I placed them in the cast iron pan, then baked them in the oven. When done, put into slow cooker. Make gravy with drippings, add flour, chicken broth and cook until thickened. Pour over meatballs in cooker. Add half-n-half 30 minutes before serving (not pictured, I left to go to the music store to teach violin lessons, family ate before I got home).
