Joy makes a variety of ice cream cones, including gluten-free sugar cones and gluten-free ice cream cups. Their gluten-free cones and cups are produced using a mixer that is dedicated to gluten-free batter. The batter lines to their ovens are thoroughly cleaned to remove any trace of gluten prior to each gluten-free production run. They use test strips that can detect gluten particles as low as 5 parts per million.
