Soak cashews in warm water for a minimum of 1 hour up to 4 hours.
Peel cucumbers and slice them into large chunks.
When ready to make the soup, drain and rinse the cashews and add them to a high-speed blender with the peeled cucumbers, garlic, sherry vinegar, olive oil and salt.
With the blender running, slowly pour in water until desired consistency is reached.
Chill soup in the refrigerator for a minimum of 1 hour.
Serve cold with extra sliced cucumbers, borage flowers, fresh herbs, cracked black pepper or anything else that makes you happy.
