RASPBERRY HOLIDAY HAM

1 (4-5 lb.) fully cooked boneless smoked ham
2 tbsp. lemon juice
1/3 c. seedless red raspberry jam
1/4 c. dry white wine
2 tsp. cornstarch
1 tbsp. butter

Score ham in diamond pattern, if desired. Place on rack in a shallow roasting pan. Bake, uncovered, in 325 degree oven for 1 3/4 hours.
Meanwhile, in small saucepan, blend wine and lemon juice into cornstarch. Add about half of the jam. Cook and stir until thickened and bubbly. Stir in remaining jam and butter. Heat and stir until butter is melted. Brush ham with raspberry glaze. Bake 10 minutes more. Spoon remaining glaze over ham. Garnish with watercress, if desired. Yield: 6-8 servings.
