* To make vanilla simple syrup, cut a whole vanilla bean in half lengthwise, and add to a medium saucepan with 2 cups water and 2 cups sugar. Bring mixture to a boil, stirring to dissolve the sugar. Reduce heat to low, and gently simmer for 3 minutes. Take the mixture off the heat, and let infuse overnight. Strain into a clean jar and store in the refrigerator for up to 2 months.
