El Niño Forces World's Top Chefs to Reinvent Menus Amid Climate Chaos

At a gastronomic festival on Mexico's Caribbean coast, the world's most celebrated chefs gathered not to celebrate their latest triumphs but to confront a shared crisis: an exceptionally strong El Niño cycle is rewriting the rules of their profession. The climate phenomenon, which disrupts global wind and rainfall patterns and triggers erratic weather worldwide, is forcing kitchens from São Paulo to Copenhagen to abandon the ingredient lists they built their reputations on and improvise weekly, sometimes daily, as staples vanish or arrive spoiled.

Alex Atala, the Brazilian chef whose São Paulo restaurant D.O.M. sources ingredients from the Amazon to reinterpret Indigenous traditions, has become accustomed to radical improvisation. For the past three years, he has written an annual menu knowing full well he will rewrite it dozens of times before the year ends. Ants, a signature element of his cuisine, are no longer reliably available; this year, he can offer them only to customers who specifically request the experience. The problem extends beyond scarcity. El Niño disrupts transportation networks so severely that fresh ingredients destined for his kitchen arrive delayed by flooded roads or wildfires, their quality already compromised. What should have been pristine is instead diminished. Atala speaks of this not merely as a logistical inconvenience but as a cultural loss—when an ingredient disappears, so does a tradition, a connection to the land and the people who stewarded it.

The Mediterranean has become a cautionary tale. Quique Dacosta, who runs a restaurant in Denia near Valencia, watched torrential rains in 2024 kill nearly 250 people and obliterate the agricultural foundation of his region. Vineyards, orange groves, and the Albufera rice paddies that supply paella—the dish that defines his cuisine—were decimated. He describes the climate crisis as a direct assault on the raw materials that form the bedrock of what he cooks. But the damage extends beyond his suppliers. When storms arrive, customers cancel reservations out of fear. His restaurant sits vulnerable, dependent on people willing to venture out into dangerous weather. "It's going to rain a lot and people just don't come anymore," he told reporters. The economics of fine dining, it turns out, are fragile when the sky becomes unreliable.

El Niño's effects are geographically uneven, creating winners and losers in unexpected ways. Roberto Solis, a chef in Mexico's Yucatan Peninsula, notes that this is the first year without hurricanes in the Mexican Caribbean. That absence, while it sounds like relief, is actually catastrophic for his seafood-centered menu. Hurricanes carry moisture and redirect ocean currents and plankton; without them, the marine ecosystem that feeds his restaurant Huniik—where he reimagines Mayan specialties—has shifted fundamentally. He is working with fish species he has never cooked before, forced to learn new techniques and flavor profiles on the fly.

Some chefs are responding with deliberate innovation. Rasmus Munk, the Danish chef at Copenhagen's Alchemist, is experimenting with chocolate alternatives because the global chocolate market itself is buckling under climate pressure. He is manufacturing a cocoa-free chocolate from brewer's spent grains—the fibrous byproduct of beer production—which serves as both a creative solution and a local alternative to ingredients that can no longer be reliably sourced. Japanese chefs like Yusuke Takada, who blends Japanese ingredients with French technique at La Cime in Osaka, are adapting to entirely new seafood selections as El Niño alters the migratory routes of fish species. In Japan, he notes, there is always product available, but the product itself is unfamiliar.

Yet innovation has limits when the underlying systems fail. Alvaro Clavijo, who runs El Chato in Bogotá, is watching cacao pulp and Andean tubers grow scarce. His deeper worry is water. Two years ago, a severe drought forced rationing that rippled through his kitchen in ways that felt impossible to manage. In a restaurant, water is not a luxury—it is infrastructure. When it becomes scarce, the entire operation becomes precarious. Dominique Crenn, a French-born chef in San Francisco whose restaurant Atelier Crenn uses its menu to communicate the gravity of the climate crisis to diners, summed up the mood among the culinary elite gathered in Mexico: El Niño is changing everything. The world's most accomplished chefs, accustomed to controlling their domains through skill and vision, find themselves instead managing scarcity, adapting to the unavailable, and watching the cultural and ecological foundations of their work erode.
