1 bottle (750 ml size) spiced rum with screw cap 8 whole vanilla beans
Remove 1/4 cup of rum from the bottle to allow for liquid displacement.
Carefully cut a slit, without piercing through, down the length of each vanilla bean. Carefully add each bean to the bottle of rum. Replace the cap and gently mix by tipping the bottle. Allow to sit in a cool dark place for 6-8 weeks. Occasionally tip the bottle to blend the flavors.
