Cornstarch does the heavy lifting in this sauce, acting as a pure thickening agent that requires a brief boil to activate its starch molecules fully. Whisking the water, ketchup, sugar, vinegar, and seasonings together before applying heat ensures the powder dissolves evenly without forming stubborn lumps. Bring the saucepan to a rolling boil while stirring constantly, maintaining this energetic bubble for a full two minutes to cook out any raw starch taste and achieve a glossy, clinging consistency. Watch for the mixture to transition from a loose liquid to a heavy glaze that coats the back of a spoon cleanly, leaving a distinct path when you draw a finger through it. Incorporating the cubed butter at this stage adds gloss and rounds out the sharp acidity of the cider vinegar and lemon juice. Once the sauce reaches this proper viscosity, fold in the sliced cooked pork and simmer only until the meat reaches an internal temperature of 165 degrees Fahrenheit throughout. When adjusting the batch size for larger gatherings, maintain the precise ratio of cornstarch to total liquid volume to prevent a watery result.
