Split the vanilla bean and scrape the seeds into a small heavy saucepan, then add the pod and butter and cook over medium-low heat, swirling the pan occasionally, until butter is browned and the aroma is nutty, about 4 minutes. Best to devote your attention to this step as browning butter can burn easily. You can extend the life of those expensive vanilla beans by not adding the pod to the butter. Instead, follow this simple recipe to make
homemade vanilla sugar which is perfect for your coffee or baking.
