Combine chocolate and cream in a medium bowl. Bring a small pot of water to a simmer over medium-low heat, then reduce heat to low. Set the bowl of chocolate over the pot of barely simmering water, making sure the water does not touch the bowl. Stir frequently until all the chocolate is melted. Remove from heat and stir in liqueur.

Transfer the chocolate to a fondue pot and keep warm over low heat or a low flame. Alternately, transfer to a small serving bowl. Serve immediately with fruit and other items for dipping.
