Prepare the pigs feet: Rinse them thoroughly under cold water and pat dry.
Layer the aromatics: Add pigs feet, onions, garlic, bay leaves, and all dry seasonings to a large pot.
Add liquids: Pour in the apple cider vinegar and enough water or broth to just cover the meat.
Bring to a boil: Heat over medium-high until boiling, then skim any foam from the top.
Simmer: Reduce heat, cover partially, and simmer for 2.5–3 hours until tender.
Add final seasonings: Stir in hot sauce, red pepper flakes, and brown sugar during the last hour.
Thicken the broth: Remove the lid for the last 20–30 minutes to let the sauce reduce.
Serve hot: Adjust seasoning as needed and ladle broth over the pigs feet before serving.
