1. Caramelized onions can be stored in the fridge for up to a week or frozen for up to 3 months.
2. FREEZER FRIENDLY: Combine the Pork Carnitas and Enchilada sauce in a ziplock bag, and place the caramelised onion in a separate ziplock bag. Freeze until required. Defrost completely before using and warm in microwave.
3. The reason I only cook one side of the Pork Carnitas is to keep the pulled pork as juicy as possible while still adding the crunch from the browning on one side.
