Using a vegetable peeler, remove the skin from the cucumber. Depending on how spicy you like things, you can remove the seeds from the jalapeno or not.
Put all ingredients in a pitcher or large jar and let sit for 1-2 hours for the flavors to meld. Serve over ice.
If you want to serve right away, muddle the cucumber and jalapeno in the bottom of a drink shaker, add the liquids, give it a good shake and then serve over ice. This is enough for two drinks. ENJOY! Drink responsibly.
