I don’t care that we got a half a foot of snow last night–that’s all the more reason to eat ice cream! So in preparation for holiday gorging (pies a la mode!!), an hour on the history and science of ice cream.

Sarah Lohman of Four Pounds Flour will unearth the stories behind our favorite ice cream treats and share some of history’s wildest bygone flavors–that may be due for a revival. You’ll be able to answer questions like: which came first, chocolate or vanilla? The ice cream sandwich or the ice cream cone? Neapolitan or liquid nitrogen?

Then, Soma will tell you the science behind making the perfect batch at home, and Big Ice Cream’s tricks for plumping up their profit margins. We’ll also track frozen desserts across the globe, from Italian gelato to dondurma, the magically stretchy ice cream from Turkey.
