Pork Loin Roast in wine. Absolutely delicious. Don't overcook!
Pork loin requires precise thermal management because its low fat content causes the muscle fibers to tighten aggressively past 145 degrees Fahrenheit. Slow cookers apply steady, low-intensity heat that dissolves collagen without boiling the surrounding liquid. Dry white wine provides essential acidity to balance the heavy sugar rub, while balsamic vinegar reacts with the exterior proteins to form a deep crust during the braise. Trimming the silver skin before cooking prevents the exterior from curling as the meat contracts.
Standard oval slow cookers hold between six and eight quarts, which often leaves too much floor space around a three-pound roast. Wide vessels cause the braising liquid to spread thin and evaporate prematurely. Pouring the wine until it reaches two inches up the side ensures the base stays submerged while the top half roasts via steam circulation. Aluminum foil can be balled up to push against the roast if the vessel is too wide, keeping the meat centered against the heat source. Strain the remaining juices into a heavy-bottomed saucepan after cooking to concentrate the sugars rapidly over medium-high heat.
