Place the jar in a dark cupboard and shake it every once in a while. Eventually, the vanilla seeds will loosen from the pod. Shake the jar once a week or every few weeks. Your vanilla extract will be ready in eight weeks.
As you begin to use your vanilla, you can top it off with a little vodka each time. Give it a shake after you refill and give it a shake before each use.
It does not need to sit for another 8 weeks.
Think of what a fabulous homemade gift this would make, it truly is the gift that keeps on giving!
