For a solid frozen ham, thaw out in the sink overnight.

Heat oven to 325 degrees F.

Remove ham from packaging and cheesecloth. Place fat side up in a baking pan. Cover sides with foil if desired.

Place in oven and bake for 1 hour.

Make glaze by combining pineapple juice, syrup, and brown sugar in a small pot on medium heat while stirring.

Dilute cornstarch with water. When glaze slowly starts to boil, add cornstarch mixture and keep stirring until thickens. Remove from heat.

After 1 hour, remove ham from oven. Using a large sharp knife, start at the corner and cut skin and most of fat off, leaving about 1/4" of fat.

Score ham in 2 different directions using diagonal cuts to be left with diamond shapes. Place as many cloves as possible in each criss cross.

Brush or spoon gaze liberally to cover the ham all around.

Using toothpicks, start placing cherries and pineapples on the ham starting on one corner and covering as much as possible. Brush on any excess glaze.

Place ham back in oven to bake an additional hour or according to your directions.
