JOEL WILLIAMS [email protected]PITTSFIELD, Mass., Nov. 28, 2019 — The transparent pumpkin pie craze began in 2017 when chefs Simon Davies and Mike Bagale of cutting-edge, three-Michelin-star, Chicago restaurant Alinea created one using “molecular gastronomy,” a modern discipline that challenges the established conventions of cooking. The pie was made via a complex process to nail down the proper flavor. According to an October 2017 article in Vogue, the chefs used a rotary evaporator to distill a fairly traditional pumpkin pie filling and create a concentrated and translucent extract with which to flavor the gelatin filling. The result is...Read full articleRelated content from Photonics MediaArticlesHigh-Throughput Imaging Reveals Multi-Particle Cellular ActivityA new software program can map the movements of multiple particles within cells simultaneously, providing insight into cellular functions that are difficult — and sometimes impossible —...Photonics.com 2/5/2024Scattering Phenomenon Could Improve Optical CommunicationsA phenomenon observed in a miniature light-scattering system composed of an ultrathin layer of silicon nitride on a chip could lead to improved optical communications and sensors.
