"Couldn't find a cucumber soup with exactly the flavors I wanted so I made up this one! It's a creamy and uniquely flavored cool cucumber soup. It is okay to have a choppy texture rather than perfectly smooth. Whichever consistency is your preference. Serve cold."
Stir buttermilk powder and water together in a bowl until smooth; pour into the work bowl of a food processor. Add standard cucumbers, English cucumber, vanilla yogurt, shallot, lemon, mint, garlic, dill, cumin, and nutmeg to the bowl.
Pulse the food processor to begin chopping ingredients before leaving on to blend soup to your desired consistency.
