Adam Gertler is on the hunt for classic desserts that have gotten modern day makeovers. Discover a shop in Chicago that uses modern-science to create any flavor combination of ice cream or pudding you can imagine -- right before your eyes! Visit a retro candy store in Austin, Texas that is re-thinking the concept of the classic soda fountain. Check out an ice cream shop in Angiers, North Carolina, serving up a frozen concoction so spicy, you have to sign a waiver just to eat it. And tour the M&M's® factory in Cleveland, Tennessee, where they are creating their latest flavor: a mouthwatering combination of sweet and salty.
