Entered for safe-keeping, adapted from Ana Patuleia Ortins, "Portuguese Home Cooking". Roast pork loin can be very dry, so this extensive marination helps to retain moisture during cooking. Use either white wine vinegar or red wine vinegar as you prefer. Note: In Portugal, they are more likely to use sweet chili peppers (massa de pimentão), not hot chili peppers; you could put some jarred marinated roasted red bell peppers in a blender to make a suitable paste. I have included directions as well for large crock pot or 6-quart or larger pressure cooker.
