In April, celebrated chef Yotam Ottolenghi traveled to Japan with his children, exploring local culinary traditions and sharing reflections on street food customs encountered around the world. Their 12-day trip included visits to Tokyo, where they experienced the seasonal cherry blossoms near Meiji Jingu Shrine and encountered a unique street food vendor operating out of a Nissan van near the temple’s entrance.

The vendor was selling yaki imo, or roasted sweet potatoes, slow-cooked over charcoal. The van played a distinctive English-language jingle, designed to attract both locals and tourists, reminiscent of ice cream trucks in Western countries. This practice, Ottolenghi noted, is a common urban tradition in Japan, with trucks traveling through neighborhoods and using music to signal their arrival and prompt residents to purchase their offerings fresh from the grill.

Ottolenghi’s account highlights a broader global pattern in street food culture, where mobile stalls, carts, and modified vehicles serve specific regional specialties, often relying on family recipes passed down through generations. For example, in Mexico City, vendors begin preparing tortillas early in the morning on flat griddles made from cast iron or clay. Corn masa is skillfully pressed and flipped amid growing queues, underscoring the staple’s cultural importance. This tradition is so highly regarded that UNESCO inscribed it on the Intangible Cultural Heritage list in 2020.

Elsewhere in Southeast Asia, the street food scene adapts to climate and local tastes. In Penang, Malaysia, the intense midday heat accompanies bustling hawker stalls, including those preparing char kway teow—stir-fried flat rice noodles cooked over extreme heat to produce signature smoky flavors. The dish often incorporates ingredients such as shrimp, dark soy sauce, lime juice, honey, and fresh herbs like cilantro, reflecting the vibrant fusion of local flavors.

Street food customs in other parts of the world also demonstrate distinct culinary approaches tied to local culture. In New York City, the simple hot dog cart operates with propane tanks and water vats to efficiently serve customers on busy street corners. Meanwhile, various regions of India offer diverse forms of chaat, a term generally meaning “to lick,” but which encompasses different savory snacks depending on the locale. In Delhi, it is commonly papdi chaat—a combination of fried wafers, potatoes, chickpeas, chutneys, and yogurt—while in Mumbai, bhel puri, made of puffed rice, sev (crisp noodles), and raw onions bound with tamarind sauce, is favored. These dishes are frequently finished with a dusting of chaat masala, a spice blend that intensifies flavors with ingredients like amchoor (dried mango powder), black salt, cumin, and chili.

Ottolenghi’s observations underscore the enduring appeal and cultural significance of street food globally. Whether through the rhythmic sounds of a Japanese sweet potato truck or the sizzling wok fires of Malaysia, street food not only sustains daily life but also offers a shared sensory experience that connects communities and travelers alike.
