Step 1

Preheat oven to 300°F. Line a small rimmed sheet pan with aluminum foil. Coat foil with cooking spray and arrange ham, flat side down, on pan.

Step 2

In a medium bowl, combine preserves, mustard, ginger, and vinegar; reserve half of glaze for serving and use the rest for basting. Brush a thin layer of glaze over all surfaces of ham. Cook, brushing with glaze every 30 minutes, until a thermometer inserted in the center of ham registers 140°F, about 2 hours. Serve warm or at room temperature.

Step 3

Serving size: 3½ oz ham and about 2 tsp glaze
