Preheat oven to 350 degrees
Place ham face down in a pan large enough to hold it and arrange your pineapple, cherries, and orange sliced as pictured above with toothpicks and set aside
In a saucepan, add brown sugar, rum, syrup, pineapple juice, and mustard and whisk together well
Allow the glaze mixture to cook for 5-7 minutes on medium heat , stirring occasionally
Spoon half of glaze over the ham and place ham in the oven for 1.5 hours
Take ham out the oven and spoon more glaze over it and place it back in the oven for another 30-45 minutes depending on the size of your ham
Remove from the oven and spoon any remaining glaze over the ham and allow it to sit for 15 minutes before removing the fruit and carving
Serve and enjoy !
