Place pork, shrimp, tamari, sherry, onions, garlic, ginger and coconut flour in a medium bowl and using your hands, massage the ingredients until incorporated. Let sit for 10 minutes.
Form the meat mixture into 2-inch diameter balls. Heat a large skillet over medium heat for 2 minutes. Add the coconut oil to the pan and swirl to coat. Place the meatballs in the skillet and cook for 3-4 minutes, until the bottom of the meatballs are golden brown. Using a spatula, turn the meatballs over and continue to cook until the second side is golden brown. Place the meatballs on a platter.
Whisk the water, orange juice, honey, vinegar, tamari, and jams together in a measuring cup. Pour the sauce into the now empty skillet. Increase the heat to medium-high, bring the sauce to a simmer and continue to simmer for 2 minutes. Whisk the arrowroot and 2 tablespoons of water in a small bowl and slowly pour into the sauce mixture, whisking constantly. Cook for about 1 minute until the sauce turns thick. Add the meatballs back to the pan and stir so the meatballs are coated with the sauce. Serve immediately.
