In Jon Snyder’s laboratory, the science experiments result in delicious gelato and sorbet flavors. Il Laboratorio del Gelato — designed to look like a lab with stark white walls and gleaming chrome machinery — has been churning out new flavors since opening in 2002 in the Lower East Side, racking up more than 300 and counting.

That kind of work means long days for Snyder, 53, who gets up “between 2:30 and 4 a.m., depending on the day and my alarm clock — which is pretty internal by now.”
