I like to use thick slices of ham in a skillet, but this would work for a whole ham in the over, just triple the recipe. It doesn't make a sauce, just a coating of flavor.
1 T coriander
1 T cumin
2 T brown sugar
1 t paprika
3 T honey
2 T cider vinegar
1 c broth
Add ingredients to skillet and bring to boil, mixing with a whisk to combine flavors. Lower temperature to medium and add ham. Cook pieces to desired level and coated with flavors.
