Add honey to a small saucepan over medium-low heat. Scrape the seeds from the vanilla pod into the honey, and then the pod itself. Stir. Warm honey until it is loose and runny, about 6 minutes, but do not allow it to come to a boil. Remove pan from heat and and let cool for 15-20 minutes. (This allows the flavor to deepen.) Transfer honey to a glass jar.
