Combine all ingredients in a medium-sized sauce pot, whisking until well-incorporated. Bring to a boil and then reduce heat to medium. Simmer over medium heat for 10 minutes and then remove from heat. Cool to room temperature.

Thaw frozen ham in the refrigerator for 24-48 hours.

Remove from refrigerator and let ham come to room temperature, about 30-45 minutes.

Preheat oven to 325 degrees F. Remove ham from foil and film. Return ham to foil wrapping and place in oven-safe roasting pan. Roll the foil down leaving 2”of the foil around the bottom of the ham.

Place roasting pan with ham in oven on a lower rack and heat uncovered for 60-75 minutes, until ham starts to brown.

During the last 15 minutes of cooking, glaze with Rum & Coke® Glaze every 5 minutes (glaze three times total).
