Cucumber soup

Last month we went to this awesome dinner called "Farmer and a Chef."  Chef Brian Johnson put together an amazing four course meal using local foods from Rhizosphere Farm and Thistles and Clover.  For the second course he served cucumber soup.  I just started liking cucumbers this year, and have never been a huge fan, but this was so yummy.  Served cold - the perfect summer soup!

Brian was nice enough to email out the recipe this week.  Can't wait to pick up some cucumbers at the Farmer's Market this weekend!

Ingredients
Two 14 to 16 ounce English (seedless) cucumbers
1/2 clove garlic, minced
1 1/2 teaspoons kosher salt plus more to taste
1 small scallion, trimmed and chopped
2 cups buttermilk or 1 cup milk plus 1 cup sour cream
1 teaspoon minced fresh mint
1 teaspoon minced fresh dill
1 teaspoon minced flat-leaf parsley
Large pinch cayenne pepper plus more to taste
Freshly ground black pepper to taste
Freshly squeezed lemon juice, to taste (optional)

Directions
Peel the cucumbers, trim the ends, cut in half lengthwise and scrape out the watery area where seeds would be. Coarsely chop. Crush the garlic and 1/4 teaspoon of the salt into a paste with the flat side of a chef's knife. Combine the cucumber, garlic, remaining salt, and the buttermilk in a blender and process until completely smooth. Add half of each of the herbs and the cayenne and pulse several times to combine. Transfer soup to a bowl, cover, and refrigerate for 1 hour or until thoroughly chilled. Before serving, season with salt, pepper, and lemon if desired. Divide among 4 soup bowls and sprinkle with the remaining herbs. Serve.
