Kelerstein and his father had the grand opening for Glyk Gelato in Parkland, Florida in July 2016. There, he debuted his favorite flavor — which he had learned studying abroad in Italy, and would soon become his signature creation — sweet corn ice cream. Kelerstein said that he was inspired by Mexican sweet corn cakes when he created the unusual gelato variety.
As of right now, Glyk Gelato has a perfect five-star score on Yelp, with reviews calling it "the best gelato I've had outside of Europe," and lamenting the fact that the sweet corn flavor always sells out well before closing.
