Cool as a Cucumber

I made my own variation of this recipe last night; I swapped out the mint for cilantro, changed the sour cream to Greek yogurt, and was heavy handed on the cayenne pepper. Also forgot the vinegar, whoops. It was fun and easy (throw everything in a blender) to make. I think it tasted really nice as far as chilled cucumber soup goes... but it would be best as a dressing, or a drizzle on something.
