Beat in the lemon zest and then add the rum. Gradually add the dry ingredients, alternating with the heavy cream and ending with the dry ingredients. Blend until the mixture is well combined. Pour batter into a well greased and floured 10 cup tube pan and bake for almost an hour. Test doneness with a skewer inserted halfway between the sides of the pan and the tube.
