In a large pot, add water, apple cider vinegar, pork belly and sea salt. Turn on heat to medium-high and bring to a boil. Reduce heat to low and cook for an additional 5 - 8 minutes. Turn off heat, drain water and let it cool for at least 20 minutes until cool enough to handle. Chop pork belly into 1/2" pieces.
On a cast iron pan over medium heat, add chicken liver. Cook for 5 minutes until no longer pink. Mash it into smaller pieces using the back of a wooden spoon. Add pork belly and cover. Let it cook for 15 - 20 minutes, stirring occasionally to prevent the bottom from burning. (NOTE: Take the pan off the heat before removing the lid to stir the pork belly. This will prevent unexpected splatters!)
Add onions, jalapeño, garlic, coconut aminos, fish sauce, onion powder and black pepper. Saute for 2 - 3 minutes. Turn off heat and mix in the coconut cream and lime juice. Crack an egg on top and mix well before serving.
Mayonnaise can be substituted for the coconut cream in this recipe.
