Mix 1 cup 75.5% Everclear and 1 cup water. Scrape out seeds from two vanilla bean pods and add to liquor-water mix. Let sit several days; invert periodically. Strain. Some seeds will get through but as long as you get the clumps out, don’t worry, since the seeds are so tiny.
Add 1 tablespoon dark brown sugar and1/3 cup sugar. Mix until sugar is dissolved. Improves with time.
