How US tech helped create modern Italian gelato
Gelato is synonymous with Italy, but its modern origins go back to a humble dairy shop in Tuscany and a couple of abandoned American World War Two freezers.
Each summer, tens of millions of international travellers descend on Italy, and many of them will order at least one gelato sometime during their stay. But chances are that very few of these visitors – or even many Italians themselves – realise that one of the most quintessentially Italian treats may never have taken off were it not for American technology.
To understand how that creamy deep-green pistachio, chocolate-striped stracciatella or sun-yellow crema made it onto your cone, you have to venture back to a modest Tuscan dairy shop and a couple of abandoned US military freezers.
Long before modern Italians were ordering gelato from beachside resorts, their ancient Roman ancestors were chilling honey-sweetened wines and fruit syrups with mountain snow, creating sorbet‑like icy treats. By the 9th Century in Sicily, the island's Arab rulers were blending snow from Mount Etna with sweetened citrus, jasmine and rosewater to make sherbet – a legacy that lives on in Sicilian granita today.
By the Renaissance, cooks across northern Italy were experimenting with fruit purées and spiced creams chilled with Alpine snow, which paved the way for Bernardo Buontalenti's 16th-Century breakthrough in Florence. The architect enriched the mixture with eggs and milk, producing a custard-like base that froze into something far silkier than the snow-filled creams that had come before, and creating the template for modern gelato.
Soon after, artisans in Florence, Venice and Sicily began producing frozen creams in micro-batches, using hand-cranked sorbettiere (ice cream makers) and natural ice harvested from snow pits. These early gelato prototypes were dense, custard-forward and unstable, melting quickly and requiring constant attention. Because freezing relied on snow, salt and manual labour, gelato-making was a hyper-local neighbourhood craft. Even when electric refrigeration arrived in the late 1920s, production remained limited due to the high cost.
