Kahlua glazed ham

I got this recipe from the head cook at a country club I used to work at. She used this glaze recipe and the ham was delicious! -Sarah 

1/2 cup brown sugar 

1/2 cup stone ground mustard 

1/2 cup Kahlua 

butt ham 

Place ham in 9x13 pan, adding 1 cup of water to bottom of pan and cover ham tightly with foil. Bake at 325 degrees 15-20 minutes per pound. About 1 hour before finished cooking cover ham with glaze. Cover with foil again and bake 30 more minutes. Remove foil and bake until thermometer reads 160 degrees inside ham.
