Bring sugar and 1 cup water to a boil in a small pot. Reduce heat, and simmer, stirring until sugar dissolves. Remove from heat, stir in grated cucumber, and let cool. Pour through a fine sieve into a bowl or large glass measuring cup, and discard solids (you should have 2 cups syrup). Cucumber syrup can be refrigerated up to 3 days.
Combine cucumber syrup, vodka, and cranberry and lime juices in a 2-quart pitcher. Cocktail can be refrigerated up to 8 hours. Serve over ice, and garnish with cucumber wedges.
Made this drink for a group of 8. Tripled the recipe. It was very refreshing and the cucumber simple syrup was awesome. I did add some club soda to the drink as I personally like a little fizzle to my drinks and it added some pizzazz!! A perfectly refreshing summer drink! Only a couple of people said it was a little sweet for them, in which case, you could always cut the simple syrup. Very easy to make and put together!
Very refreshing & summery! One thing to note...if you'd like it more pink & less orange you should peel the cucumber before grating it.
