Horseradish Infused Vodka -- Part 1

Well this weekend, I am fairly time constrained, so I was looking for a project that would be interesting but not take much time.  I recently was at a russian bar in St. Paul, MN and had some wonderful horseradish infused vodka and decided to make some.  Now I have experimented with infusing vodka before making lemoncello, so I had an idea of how to start.  Peeled the horseradish and cut into "sticks" and placed in the vodka to set for 10 days.  Really did not have an idea on how much to put in, so that part is an experiment.
