When Clarence Birdseye Tasted the Trout That Had Been Frozen by Inuit Fishermen, It Changed the Way We Buy Food

In 1912, a 25-year-old Brooklyn native with an adventurous streak journeys to the icy reaches of northeast Canada, where he spends the better part of five years learning Indigenous ways. One particular practice fascinates him: Inuit fishermen’s method for preserving fish, which involves simply pulling a trout out of a hole in the ice and letting it freeze almost instantly in the minus-30-degree air. When thawed and cooked, the fish tastes remarkably fresh. The young man has just learned the trick to freezing food in a palatable way, which will bring him a fortune in the decades to come. His name is Clarence Birdseye. The key to maintaining freshness, Birdseye realized, was crystallization. When a food freezes slowly, the liquid within it forms large ice crystals, which damage its cell structure. The result when thawed: a leaky, grainy, mushy product, which was the only kind of frozen food available in the United States in the early 1900s. Flash-freezing, however, results in tiny ice crystals, preserving the food’s texture and flavor.

That discovery led to the creation of the Birds Eye company in 1923, opening the door to what is now an almost $300 billion global frozen-foods industry, and to a larger universe of ready-made, packaged and processed foods. But Birdseye’s innovations went far beyond simply importing the quick-freeze method. His ideas were so new that he had to pioneer every step of production, inventing machines along the way. The first of his more than 200 patent applications was for insulated containers to keep his products cool; he also developed new waterproof inks, glues and cellophane that could withstand freezing and thawing.

A Popular Science Monthly headline called Birdseye’s products “exactly like fresh” in September 1930; two years later, the New York Times declared his innovations a “scientific miracle,” but Birdseye still faced challenges. To overcome the stigma of frozen goods, he called his first line of products “frosted foods.” Another early barrier was infrastructure: Electric refrigerators began to replace iceboxes only in the late ’20s, and the “freezer compartment” was just a tiny slot for ice-cube trays. Free-standing home freezers were rare, and there were no trucks or train cars equipped to transport frozen foods—or warehouses cold enough to keep them.
