One of our family's favorite desserts! We would often make this on New Year's Eve. As a child it was very exciting to watch our dessert burst into flames before eating it (and to have alcohol in a dessert! Don't worry it cooks off). Make sure that the rum warms nicely before you light it otherwise the flames won't be as impressive. My mom would always select a high quality vanilla bean ice cream-- there is no better vanilla in my opinion.
