1. Preheat oven to 350 degrees.
2. Line a shallow roasting pan with aluminum foil.
3. Place the ham on the rack in the roasting pan.

6. Reduce heat and simmer uncovered until the wine is reduced to 1/2 cup.
7. Remove from the heat and discard the thyme sprigs.
8. Stir in the peach preserves, mustard and brown sugar.
9. Brush half of the glaze mixture over the ham.
10. Bake uncovered for 1 hour and 30 minutes, basting with the remaining mixture every 30 minutes.
11. Cover loosely with aluminum foil and bake 30 minutes or until the thermometer reads at least 140 degrees.
12. Let stand 15 minutes.
13. Slice & serve
14. Enjoy!
