A VERY non-traditional white gazpacho recipe from Food & Wine. I've doubled the recipe as it called for strange amounts (like 1/2 a cauliflower). Cooking time is chilling time recommended, however I would chill overnight for best results.
In a large saucepan of boiling salted water, cook the cauliflower until tender, about 8-10 minutes. Drain, rinse under cold water until cool and drain well.
In a blender, combine 1 1/2 cups of ice-cold water with half of all the ingredients except the last three; blend until smooth. Add 1/3 cup olive oil and pulse just until incorporated. If necessary, add more water to thin the gazpacho. Pour into a container suitable for chilling and repeat with the second half of ingredients. Season the soup to taste with salt and refrigerate until chilled, about 1 hour (or overnight).
Preheat the oven to 350°. Spread the remaining 1/2 cup of slivered almonds in a pie plate and toast for about 6 minutes, until fragrant and lightly golden. Ladle the gazpacho into bowls. Garnish the soup with the toasted almonds and the finely diced cucumber and serve.
