In a medium mixing bowl, combine sour cream, mayonnaise, cotija cheese, lime zest and juice, elote seasoning, and minced garlic. Whisk until smooth and creamy, then set aside.

Thaw the frozen corn in a microwave-safe bowl for 2-3 minutes, stirring halfway through. Drain and let cool.

Wash and slice the mini cucumbers thinly, then transfer them to a large mixing bowl.

Chop the cilantro and mince the red onion, then add to the bowl with cucumbers along with the thawed corn.

Pour the prepared dressing over the cucumber mixture and toss gently until evenly coated.

Season with sea salt to taste, starting with about ¼ teaspoon.

Serve immediately in a serving bowl, garnishing with extra cilantro if desired.
