Think of these as the new onion rings: crispy, fried, and completely addictive.
Combine the mayonnaise, chives, and seafood seasoning in a small bowl; set aside.
Heat the oil in a large pot until the temperature reaches 350° F on a deep-fry thermometer.
Whisk 1 cup of the flour, the buttermilk, egg, 1 teaspoon salt, and ½ teaspoon pepper in a large bowl.
In a separate bowl, toss the zucchini with the remaining ½ cup flour. Coat in the batter. Fry, in batches, until golden, 4 to 6 minutes.
Serve the zucchini with the dip and lemon wedges.
