Acid is the primary driver in a citrus-heavy marinade, but because citrus juice lacks the molecular mass to break down dense connective tissue efficiently on its own, the substantial volume of extra-virgin olive oil acts as a hydrophobic barrier that keeps the aromatics adhered to the meat surface while the organic acids slowly denature the exterior proteins. Oranges and limes supply citric and ascorbic acids, which lower the pH of the meat's outer layers, tenderizing the muscle fibers without denaturing them to the point of structural mushiness provided the immersion time stays under twenty-four hours. Roasting begins at a high initial temperature of 425 degrees Fahrenheit to initiate Maillard browning reactions between the amino acids and reducing sugars in the citrus juice before dropping the ambient heat to finish cooking the interior evenly. Resting the carved roast for twenty minutes under foil allows internal muscle fibers, which tightened under heat and forced moisture outward, to relax and reabsorb escaping juices. Doubling or halving this recipe requires proportional adjustments to surface area and pan sizing rather than linear time scaling, as a larger meat mass demands extended oven time to reach the target internal temperature of 160 degrees.
