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

Thinly slice mini cucumbers into rounds and arrange them in a large mixing bowl.

Thaw frozen corn in the microwave for 1-2 minutes, drain excess water, and add to the salad.

Finely chop cilantro and mince red onion. Add both to the bowl with cucumbers and corn.

Pour the dressing over the salad and gently toss until well coated.

Season with sea salt to taste and give a final toss.

Serve immediately or refrigerate for about 30 minutes before serving.
