Melt the butter with the sugar

• Place the butter and light brown sugar in a saucepan.
• Melt over low heat, stirring until the sugar dissolves.

Add the remaining glaze ingredients

• Stir in the cherry preserves, orange juice and bourbon.
• Zest the orange into the pan, then halve it and squeeze in all its juice.
• Whisk until smooth and well combined.

Smoke the glaze under the ham

• Set the pan on the smoker underneath the ham so the drippings fall into it.
• Let it cook for about two and a half hours, stirring occasionally.
• Every half hour, baste the ham with the glaze.

Finish and serve

• The glaze will thicken as it reduces; keep stirring as it cooks.
• Pour the remaining glaze over the ham to your liking.
• Once carved, spoon a little more glaze over each slice.
