When buying a freezer, most of us consider the size and energy usage of a new model, but not other factors that can influence freezer burn and flavor. In this edition of PM’s Most Useful Podcast Ever, we play with a flash-freezing machine made by a scientific supply company and talk to Penn State University food scientist Luke LaBorde to find out how frozen food works and what you can do to keep stored meats and vegetables tasty. We also talk to Popular Mechanics’ Senior Home Editor Roy Berendsohn about hard and soft water, and consider whether we’d use Phiaton’s BT 220NC headphones, Flugz Hearing Protection Earplugs, and a very strange food substitute called Soylent.This episode is sponsored by Braintree.  To learn more, and for your first $50,000 in transactions fee-free, go to braintreepayments.com/USEFUL
