I’m sorry to hear that. Because this is cooked in the Instant Pot and the meat isn’t being dried out on a grill or in the oven – it sounds like your tenderloins were pumped full of water and additives prior to purchasing. They will release those fillers when cooked. Unfortunately, it is a common practice when manufacturers are trying to make the products bigger and heavier to increase profits in times like these – while still giving you the same amount.
