The 16th-century Portuguese origin of Japan's most famous fried delicacy
While we associate tempura with Japanese tradition, its roots lie in the religious fasting rituals of Portuguese Jesuits. This culinary evolution transformed a heavy, seasoned Catholic dish into the light, crisp, and airy masterpiece found in Tokyo's modern food stalls.
The history of tempura begins in the 16th century via the Nanban trade. Portuguese missionaries brought a Western-style technique of coating food in flour and frying it. At the time, the dish was closely linked to the Catholic liturgical calendar. The name likely derives from the Latin 'tempora', referring to 'Ember Days' or 'Lent'—periods when meat was avoided in favor of fish and vegetables. Unlike the modern version, these early fritters were heavy, using a thick batter of flour, sugar, and sake, fried in lard.
As the technique moved into Japan, particularly around the Tokyo Bay area in the early 17th century, it underwent a significant transformation. The 'Edo-style' or 'Tokyo-style' emerged from yatai (food cart) culture. To preserve the delicate taste of fresh seafood, cooks stripped the batter down to just flour, eggs, and water, removing all seasonings. This era also saw the development of the signature texture: by mixing the batter minimally with cold water using chopsticks, cooks prevented the activation of wheat gluten, ensuring the result was fluffy rather than dough-like.
The evolution of tempura was also shaped by urban necessity. During the Edo period, serving deep-fried foods indoors was prohibited because the hot oil posed a significant fire hazard to Japan's paper and wood buildings. This forced tempura to become a popular outdoor fast food, often served on skewers. While the modern recipe was first documented in the 1671 cookbook 'Ryori Kondensho', tempura has since transitioned from a street-side snack to a high-class cuisine, though it maintains its fundamental identity through its light, pale, and crunchy structure.
