To make a small batch of vanilla bean ice cream, you will need 1 small vanilla bean pod. Split the vanilla bean down its length using a very sharp knife and scrape out the seeds with the tip of the knife. Fold the seeds into the ice cream. You can purchase vanilla bean pods in the spice aisle of many grocery stores. Pro Tip: Don't throw the empty vanilla pod away. You can use it to infuse the milk with a subtle vanilla flavor and add it to your coffee.
