Step 1

Peel the cucumbers and cut off ends. Cut them in half the long way and using a knife and a spoon, scoop out the seeds and discard. Lay them cut side up on paper towels and sprinkle on the ½ teaspoon of kosher salt and let sit while you prepare the other ingredients, about 15 minutes. Turn the cucumbers cut side down and let sit another 15 minutes. Reserve a half cup and cut into small pieces to use as a garnish. Cut the remainder into large chunks to be pureed.

Step 2

In a blender or food processor, place sour cream, yogurt, red onion, garlic, jalapeno, cumin, coriander, cilantro, lime zest, lime juice, sea salt and white pepper.

Step 3

Rub the cucumbers dry with more paper towels and add to the blender and puree the mixture until smooth.

Step 4

Serve immediately in glasses or small bowls garnished with chopped red onion and chopped cucumber. Soup may be chilled before serving as well.
