Tenkasu (Tempura Crisps)

What is Tenkasu (Agedama)

Tenkasu (天かす) or Agedama (揚げ玉) is crunchy scraps/crumbs made from tempura batter. It is commonly used in the fillings for Takoyaki, Okonomiyaki, and Hiroshimayaki as it gives fluffier texture. It’s also used as toppings for Tanuki Udon or Soba to give an extra crunchy texture.

1 Tbsp of Tennkasu is 3-4 grams.

Where to Get Tenkasu?

You can purchase a packaged pre-made tenkasu and it’s usually in the dried food section of Japanese/Asian grocery stores or Amazon.

How to Store It

Once you open the package, I usually keep the package in a freezer, but refrigeration is a must.

How to Make Tenkasu (Agedama)

For those of you who can’t purchase Tenkasu at grocery stores, it is easy to make your tenkasu from scratch at home with common ingredients found in the grocery stores. You can make a large batch and store in the freezer for up to 2-3 months.

Instructions
 

  • In a medium pot, heat 2 cups neutral oil over medium-high heat to 350ºF (180ºC).
  • Mix 4 Tbsp cake flour and 4 Tbsp iced water in a medium bowl with cooking chopsticks until the flour is just incorporated. Do not overmix; try not to develop the gluten.
  • When the oil is 350ºF (180ºC), deep-fry the Tenkasu in batches. Scoop some batter with your cooking chopsticks, hold the chopsticks over the pot, and let the drops of batter fall into the hot oil. The batter will submerge and immediately pop up on the surface and float to the edge of the pot. Once the batter turns slightly golden, about 5–10 seconds, use a fine-mesh skimmer to scoop and transfer them to a plate lined with a paper towel. Repeat with the remaining batter.

To Serve

To Store

  • Store the Tenkasu in an airtight container and keep it in the refrigerator for up to 1 week and in the freezer for up to 2–3 months.
