In 1543, three Portuguese sailors became the first Europeans to reach Japan. Over the following decades, Portuguese Jesuit missionaries and traders established a presence in Nagasaki, bringing with them a dish eaten during Lent and Ember Days (tempora in Latin — the fasting periods when Catholics abstained from meat): peixinhos da horta, battered and fried green beans. The Japanese adopted the technique, refined it, lightened the batter, expanded it to seafood and vegetables, and created what is now one of the defining preparations of Japanese cuisine. The word "tempura" derives from the Latin "tempora."
The Portuguese original (peixinhos da horta) used a thick batter of flour, eggs, and sometimes sugar, fried in lard. The Japanese transformation was radical: iced water instead of room-temperature, minimal mixing (leaving lumps for crispness), sesame oil instead of lard, and an obsession with temperature control that the Portuguese original never demanded. Japanese tempura-ya (specialist tempura restaurants) fry each piece individually, serve it immediately, and judge their craft by the lightness and crispness of the batter — a standard that would be unrecognisable to the Portuguese Jesuit who first fried green beans in Nagasaki.
- **The Japanese did not copy tempura — they invented it.** The Portuguese provided the concept (batter-frying during fasting periods). The Japanese created the technique (ice-cold batter, minimal mixing, precise oil temperature, immediate service). What we call tempura is Japanese, not Portuguese. - **The batter must be cold and undermixed.** Lumps are correct. Overmixed batter develops gluten, which produces a chewy, bread-like coating rather than the shattering crispness that defines tempura. Use iced water. Mix with chopsticks for 3–5 seconds. Stop. - **Oil temperature is 170–180°C.** Too hot and the batter burns before the interior cooks. Too cool and the tempura absorbs oil and becomes greasy.
