Step 1Pour the cream in a saucepan.
Step 2Using a sharp knife, slit one vanilla bean lenghtwise and scrape out the tiny seeds. Place the seeds and the vanilla bean into the saucepan. Add two cinnamon sticks (or use 1/2 tsp ground cinnamon). (If you don't have vanilla beans, add 2 tsp vanilla extract together with the rum in step 11).
