* If you can't find an Armenian cucumber at your local grocery store or farmer's market, you can simply use a regular cucumber for a similar flavor. Just make sure you peel the skin off of your cucumber if it has a wax coating.
** The amount of vodka you use will really depend on the size of your cucumber. The Armenian cucumber that I had purchased was pretty large, so I needed a lot of vodka. This is not an exact science, so feel free to eyeball the quantity. Just make sure your cucumber ribbons are submerged in the vodka.
*** You can shake the jar every couple of days if you would like, but it isn't necessary. Try not let the mixture steep for longer than 7 days for it will start taking on a bitter flavor. I started tasting the vodka on day 4 to check the flavor.
