Get a head start flavoring your pork roasts with this tropical pork injection marinade. All you’ll need is a meat injector, a few ingredients, and you’re good to go!
This tropical injection marinade adds flavor and moisture to all cuts of pork. The pineapple juice and cider vinegar together form an incredible flavor enhancer and meat tenderizer. Use this injection solution on leaner cuts like pork loin roasts or tough cuts like pork shoulder.
Please keep in mind that since this tropical pork injection contains two types of acids and rum, you will need to adjust the marinating time. Plan on 4-6 hours, rather than 12 or more. We recommend pairing this amazing injection marinade with a sweeter, dry rub like our Honey BBQ Rub. Now, let’s make this marinade, shall we?
