  1. Chop the chocolate into medium-sized pieces. Place in a food processor and process until fine.
  2. Add sugar and espresso powder and process for about 10 seconds.
  3. With motor running, add 1 cup of boiling water through the feed tube and continue to process another 10 seconds.
  4. Transfer to a heavy saucepan. Add the remaining 1 cup of boiling water and stir over moderate heat until the mixture comes to a boil. Reduce heat and simmer, stirring occasionally, for 5-6 minutes. Remove from heat.
  5. Let cool to room temperature. Stir in vanilla and rum. Refrigerate several hours, or overnight.
