In a blender, combine corn kernels, cucumber, yellow bell pepper, garlic, and shallot.
Blend the mixture until smooth.
Add olive oil, white wine vinegar, water, salt, and pepper to the blender.
Blend again until all ingredients are fully incorporated.
Pour the mixture into a large bowl and whisk to ensure even texture.
Cover the bowl and refrigerate for at least 1 hour to allow flavors to meld.
Before serving, stir in the chopped basil and cilantro.
Pass the gazpacho through a sieve for a smoother texture, if desired.
Serve chilled in bowls, garnished with diced avocado.
Notes
For the best flavor, use fresh, sweet corn when in season. If using frozen corn, ensure it's fully thawed before blending. Adjust seasoning to taste, and feel free to add a pinch of chili flakes for a spicy kick.
