In a small mixing bowl, whisk together buttermilk and eggs.
Combine the two, folding until just mixed. Do not over mix the batter.
Cover and refrigerate for a minimum of 30 minutes, but up to 24 hours.
When ready to cook, preheat oven to “warm” setting.
Pour oil to a depth of 2" in a 6-qt. Dutch oven or large sauce pan and heat over medium-high heat until a deep-fry thermometer reads 350°.
Drop 1 tablespoon of batter into the oil. Continue, working in batches and being mindful to not crowd the pan.
Fry until outsides are a crispy, golden brown, approximately 3-4 minutes.
Remove to a wire rack over paper towels. Transfer to a baking sheet in the warm oven to keep heat until all are fried and ready to serve.
Serve with desired dipping sauce.
