The foods everyone thinks are seasonal but really aren’t
Refrigeration, global trade and industrial production have made many once-seasonal foods available year-round, while holiday demand still shapes what shoppers see.
Modern supply chains and global trade have decoupled food availability from seasonal harvests, meaning grocery aisles no longer strictly reflect what the regional harvest allows for most Americans.
Refrigeration and global trade rewrote the supply chain within a few generations, yet food traditions formed around constraints like harvest windows that stopped being accurate long ago.
Peru accounts for roughly 30% of total U.S. asparagus imports, and in 2024, America imported 515.4 million pounds of asparagus from all sources, erasing the traditional spring supply gap.
Only about 5% of the American cranberry crop is sold fresh, while 95% goes to processing, yet every ingredient in holiday Eggnog has been available year-round for generations.
Archaeological evidence confirms humans avoided summer oysters for at least 4,000 years; while modern aquaculture and Refrigeration make year-round consumption safer, the traditional R-month guideline remains a persistent, if outdated, rule.
