This is a recipe for a pork tenderloin.
Why does the meat need to marinate in a plastic bag rather than a metal bowl? Acidic ingredients like apple cider vinegar react chemically with reactive metals such as aluminum or cast iron, which transfers a metallic taste to the protein. A heavy-duty polyethylene zip-top bag eliminates this reaction while keeping the liquid in constant contact with the surface of the meat.
Acidity also breaks down surface proteins during long resting windows. Because this marinade features a high proportion of vinegar, limit the soak to twelve hours maximum to prevent the outer millimeters of the muscle from turning mushy. When transferring the meat to the oven, utilize a heavy rimmed baking sheet rather than a flat pan to catch escaping juices that would otherwise smoke on the oven floor.
Insert an instant-read digital thermometer horizontally into the thickest part of the tenderloin to avoid touching any internal fat pockets. Pull the meat from the heat source when internal sensors read 150 degrees Fahrenheit. Residual carryover cooking will push the final temperature up to 155 degrees while the meat rests undisturbed on a wooden cutting board for ten minutes.
Standard table salt contains anti-caking agents and finer grain sizes that dissolve too aggressively when measured by volume. Kosher salt flakes distribute evenly through viscous mixtures of honey and Dijon mustard without creating overly salty pockets.
