While ham is smoking, it is time to prepare the baste. Combine the orange juice, stock, honey, maple syrup, and Dijon mustard in a saucepan. Simmer on medium high for 2 minutes, stirring often. Reduce heat to medium and continue simmer for an additional 3-4 minutes. Taste baste and determine if more than a pinch of salt is needed. Add salt and stir through. Remove glaze from heat and add 2 tablespoons of butter. Stir until it has melted through. Cover saucepan and keep glaze slightly warm before using.
