Combine all of the meatball ingredients and mix thoroughly.
Form into 16 meatballs.
Bake in a 375 degree (F) oven for 15 minutes.
While the meatballs are baking heat the olive oil in a medium saucepan.
Add onions and garlic and cook for 2 - 3 minutes until soft.
Add the cardamom, chili's, cumin, coriander, salt, turmeric, ginger, cinnamon, mustard powder, bay leaves and cloves to the onions.
Cook for about 2 minutes.
Add the water, apple cider vinegar, ketchup and sweetener to the pan and bring to a boil.
Reduce the heat and simmer for about 10 minutes.
Remove the meatballs from the oven and add them to the sauce.
Simmer the meatballs in the sauce, covered and over low heat for at least 30 minutes - or up to an hour.
The longer they simmer, the more flavor they will take on from the sauce.
Apple cider vinegar provides the crucial acidity required to balance the heavy pork fat and warm spices, acting as both preservative and tenderizer in this heavily seasoned dish. Without a proper acid backbone, dishes relying on ground pork and warming spices taste muddy rather than sharp. Ground pork benefits from thorough mixing with almond flour and egg to maintain structural integrity before baking at 375 degrees Fahrenheit for 15 minutes.
Freezer and Make-Ahead Performance
Freezing cooked meatballs directly in their vinegar-based sauce works surprisingly well because the high acid content prevents the spices from degrading during storage. Cool the mixture completely in a shallow container before transferring it to airtight freezer-safe containers for up to three months. Thaw the frozen batch overnight in the refrigerator rather than on the counter to prevent uneven temperature zones that encourage bacterial growth. Reheat the thawed meatballs gently in a covered saucepan over medium-low heat, adding a tablespoon of water if the sauce thickens excessively during storage.
Leftover Transformations
Extended refrigeration allows the cardamom, cloves, and cinnamon to penetrate deeply into the pork proteins, making second-day portions noticeably more pungent than freshly cooked batches. Serve chilled leftovers sliced thin inside sandwiches or break them apart into scrambled eggs for a morning meal.
