01 - Bring a saucepan of water to a rolling boil. Add 2 cups of the corn kernels and blanch for 2 minutes until tender-crisp. Drain immediately and transfer to an ice bath to halt cooking. Drain again and set aside. Reserve the remaining 1 cup of uncooked corn kernels for garnish and added texture.
02 - In a blender, combine the blanched corn, diced cucumber, yellow bell pepper, tomatoes, shallot, garlic, chilled vegetable broth, olive oil, lime juice, sea salt, black pepper, and ground cumin. Blend on high until completely smooth and silky.
03 - Taste the blended soup and adjust salt, pepper, or lime juice as needed. For a refined, velvety texture, pass the soup through a fine-mesh sieve, pressing with a spatula to extract all liquid. Discard any remaining pulp.
04 - Transfer the gazpacho to a covered container and refrigerate for at least 1 hour. This resting period allows the flavors to meld and deepen. The soup can be prepared up to a day in advance for even better results.
05 - Ladle the chilled gazpacho into individual bowls. Top each serving with the reserved raw corn kernels, a sprinkle of chopped chives or cilantro, diced avocado if desired, and a gentle drizzle of extra-virgin olive oil. Serve immediately.
