Pour the beer over the ham and bake, uncovered, 30 minutes to the pound in an oven preheated to 425 degrees. Just before serving, decorate with candied cherries and slices of pineapple fastened to the ham with toothpicks. Return to oven to brown for 20 minutes. Use the liquid in the pan as a sauce for the ham.
Allow 1/3 pound ham per person to be served, and keep in mind that leftover ham has a multitude of uses, as well as being a meat that retains its flavor well in the freezer.
