Imagine stumbling upon a hidden paradise where fruits you’ve never even heard of grow in abundance—a place so extraordinary, it’s been dubbed the ‘Garden of Eden.’ But here’s where it gets controversial: could this Spanish farm hold the key to saving citrus from the brink of climate-induced extinction? Let’s dive in.
It all began when chef Matthew Slotover, founder of the acclaimed London restaurant Toklas (a favorite of Nigella Lawson), ventured to Spain’s east coast. There, he discovered the Todolí Citrus Foundation, a nonprofit farm boasting the world’s largest private collection of citrus—over 500 varieties. And this is the part most people miss: these rare fruits might carry genetic secrets that could revolutionize how we grow citrus in a warming world.
Slotover was mesmerized. ‘It was like stepping into the Garden of Eden,’ he recalled. ‘I knew oranges, lemons, limes—but tangelos, finger limes, citrons, pomelos? These were revelations.’ His menu at Toklas, inspired by European flavors, now features exotic gems like Rangpur lime, Spanish sweet limetta, and Shikuwasa mandarin—ingredients so unique, they’ve become a sensation among London chefs.
Here’s the twist: before Slotover’s discovery, the Todolí farm had no commercial ambitions. ‘We’d give the fruit to friends or an Italian ice-cream maker,’ said owner Vincente Todolí, former director of Tate Modern. Now, thanks to Slotover’s collaboration with organic supplier Shrub, these rare citrus varieties are gracing plates across London, from finger limes (aka caviar limes) with their bursting zesty pearls to the fragrant Borneo lumia.
But Todolí isn’t just about flavor—it’s a sanctuary. By shunning pesticides and embracing ancient Arab irrigation techniques, the farm has become a haven for frogs, goldfinches, and bees. Bold claim: their gene bank of hundreds of citrus varieties could be the key to future-proofing citrus against climate change. ‘Eventually, citrus might thrive north of the Pyrenees while struggling in the south,’ warns technical director Óscar Olivares-Fuster.
Take the trifoliate orange, for instance. This small, sharp fruit sheds its leaves in winter, making it cold-resistant—a trait scientists could use to engineer hardier citrus varieties. Or the calamansi, a tangy Filipino fruit, and the Valentine pomelo, a sweet California favorite, both now grown alongside 40 Japanese varieties like the Kiyomi tangor.
Thought-provoking question: As climate change reshapes agriculture, should we prioritize preserving rare varieties like these, even if they’re not commercially viable? Or is the focus on mass production more practical? Let us know in the comments—this conversation is just getting started.
