Wikipedia: Tempura
Tempura (天ぷら or 天麩羅 tenpura, [tẽ̞mpɯᵝɾa]) is a Japanese dish usually consisting of seafood or vegetables that have been battered and deep fried. The dish was influenced by fritter-cooking techniques introduced by Portuguese residing in Nagasaki in the 16th century, and the name “tempura” relates to that origin.

Etymology
The word “tempura”, or the technique of dipping fish and vegetables into a batter and frying them, comes from the word “tempora”, a Latin word meaning “times”, “time period” used by both Spanish and Portuguese missionaries to refer to the Lenten period or Ember Days (ad tempora quadragesima), Fridays, and other Christian holy days. Ember Days or quattuor tempora refer to holy days when Catholics avoid red meat and instead eat fish or vegetables. The idea that the word “tempura” may have been derived from the Portuguese noun tempero, meaning a condiment or seasoning of any kind, or from the verb temperar, meaning “to season” is also possible as the Japanese language could easily have assumed the word “tempero” as is, without changing any vowels as the Portuguese pronunciation in this case is similar to the Japanese.
