Tenkasu vs. Agedama: Tempura Bits
Tempura is a traditional Japanese food made by deep-frying one piece of ingredient covered in a batter of hen’s eggs and wheat flour.
The scraps of deep-fried Tempura batter generated in the cooking have the name Tenkasu (天かす) or Agedama (揚げ玉) in Japan, known as Tempura bits or Tempura crumbs in English.
Tenkasu vs. Agedama
Tenkasu and Agedama are the same things. But sometimes, the latter is distinguished from the former.
Tenkasu (天かす: meaning Tempura crumb) is originally a by-product generated in the cooking process of Tempura.
Tempura restaurants have lots of Tenkasu bits every day unsuitable for preserving, and they usually discard them as food waste.
However, we sometimes use those flakes as a topping for Udon and Soba noodle soups and put them in Onigiri rice balls.
By the way, when describing Tempura bits, we Japanese use the word Tenkasu more commonly than Agedama.
On the other hand, we tend to call commercial Tempura bits (intentionally produced to sell as products) Agedama (揚げ玉: meaning deep-fried ball).
It takes time and labor to make Agedama, whose ingredients may include shrimps or chopped squid to improve the taste and flavor.
Compared to Tenkasu, Agedama is the word for Tempura bits often used in East Japan, especially in the Kanto region around Tokyo.
