How to Make It
Stir together cornmeal, flour, salt, and pepper in a large bowl. Toss turnips in buttermilk; transfer to cornmeal mixture, and toss to coat. Shake off excess.
Pour canola oil to a depth of ¼ inch in a large skillet; heat over medium. Cook turnips, in batches, in hot oil, until golden brown, about 5 minutes, turning occasionally.
Meanwhile, stir together ketchup, chipotle peppers, adobo sauce, and apple cider vinegar. Sprinkle fries with chives, and serve with ketchup mixture.
