Why does fresh pineapple behave differently than canned fruit in a slow-cooked braise? Raw pineapple contains bromelain, a proteolytic enzyme that actively breaks down protein bonds during the initial hours of cooking. Canned fruit undergoes thermal processing that neutralizes this enzyme, yielding a strictly sweet flavor profile without the structural softening effect. Puréeing the fresh fruit directly with chipotles, chili powder, and aromatics creates an acidic marinade that penetrates the two-inch pork cubes effectively. Bone-in cuts can be used, but boneless pork shoulder ensures uniform weight distribution and predictable rendering throughout the long cooking cycle. Cutting the shoulder into consistent two-inch chunks maximizes surface area exposure to the blended adobo mixture before heat is applied. Letting the pork cook undisturbed on low for eight to ten hours ensures the collagen fully gelatinizes into the surrounding liquid. Once the meat shreds readily under the tines of two forks, folding the strands back into the pan juices restores lost moisture before assembly. Corn tortillas require a dry skillet heated over medium-high heat for thirty seconds per side to achieve pliability without splitting.
