Boil fresh corn for about 5 minutes until tender, then cool in cold water.

In a large mixing bowl, combine cooled corn, diced crispy bacon, and finely sliced green onions.

In a separate bowl, whisk together mayonnaise, sour cream, apple cider vinegar, sugar, salt, and pepper until smooth.

Pour the creamy dressing over the corn and bacon mixture, and toss gently to coat.

Fold in crumbled feta cheese if using.

Taste and adjust seasoning as needed before chilling.

Cover and refrigerate for at least 30 minutes to allow flavors to meld.

Before serving, give a gentle stir and garnish with fresh herbs.
