So, whether you’re a food enthusiast, a home cook, or just curious about Japanese cuisine, keep reading to learn more about tenkasu.
What is Tenkasu?
Tenkasu (天かす), also referred to as “tempura bits” or “tempura crumbs,” are the crispy bits of batter left over from frying tempura. Tempura itself is a Japanese dish where seafood, vegetables, and sometimes even other proteins are coated in a light batter and deep-fried. When the tempura is fried, some of the batter will detach and float in the oil, creating small, crispy bits. These bits, called tenkasu, are collected and used as an ingredient to add a crispy texture and flavor to other dishes.
The light and airy texture of tenkasu make it an excellent addition to various recipes, contributing an extra crunch and a subtle flavor that complements both savory and sweet dishes. Tenkasu is often made from a mixture of flour, cornstarch, water, and sometimes egg. The batter is designed to create a light and crispy texture when deep-fried, making the tenkasu bits an ideal complement to a wide range of Japanese dishes.
The Origins of Tenkasu
Tenkasu’s origins can be traced back to the development of tempura in Japan. Tempura itself has a fascinating history that dates back to the 16th century. While tempura is often considered a traditional Japanese dish, its roots lie in Portuguese cuisine. Portuguese missionaries introduced deep-frying techniques to Japan, which led to the development of tempura. The use of battered and fried food soon became a popular cooking method in Japan, and tempura evolved into the dish we know today.
As tempura grew in popularity, so did the discovery of the delicious little bits of fried batter that would come to be known as tenkasu. While initially considered a byproduct of tempura cooking, chefs quickly realized that these crispy bits could be used as an ingredient in their own right, adding texture and flavor to various dishes.
Uses of Tenkasu in Japanese Cuisine
Tenkasu is a versatile ingredient that can be used in a variety of Japanese dishes. Its light, crispy texture and slightly savory flavor make it a favorite in many recipes. Here are some of the most common uses of tenkasu in Japanese cuisine:
1. Okonomiyaki (Japanese Savory Pancakes)
One of the most popular uses for tenkasu is in okonomiyaki, a savory pancake that is commonly found in Japanese cuisine. Okonomiyaki is made by mixing flour, eggs, shredded cabbage, and other ingredients such as pork, shrimp, or beef into a batter. The batter is then cooked on a griddle, forming a pancake-like dish. Tenkasu is often added to the batter or sprinkled on top to give the dish a delicious crunch. The crispy bits contrast wonderfully with the soft and tender pancake, adding both texture and flavor.
2. Takoyaki (Octopus Balls)
Another beloved dish that uses tenkasu is takoyaki, a popular street food in Japan. Takoyaki are small, round balls made from a batter containing octopus pieces, green onions, and other seasonings. The batter is cooked in a special takoyaki pan, and tenkasu is often added to the batter for extra crunch. When cooked, the takoyaki balls are crispy on the outside and soft on the inside, thanks in part to the addition of tenkasu.
3. Soba and Udon Noodles
Tenkasu can also be used as a topping for both soba and udon noodles, two types of traditional Japanese noodles. The crispy bits of tenkasu add a delightful contrast to the soft and chewy noodles, enhancing the overall texture of the dish. Tenkasu is often sprinkled on top of the noodles along with green onions, pickles, or grated ginger. It can be used to add a burst of flavor to both hot and cold noodle dishes.
4. Tempura Udon and Tempura Soba
In addition to being used as a topping for soba and udon noodles, tenkasu is frequently used in tempura udon or tempura soba. These dishes feature a flavorful broth with noodles, accompanied by tempura vegetables and shrimp. The addition of tenkasu brings an extra layer of crunch to the dish, making it even more satisfying.
5. Rice Dishes
Tenkasu can also be sprinkled over donburi rice dishes, adding a delightful crunch and umami flavor. Ten-don, for example, is a type of donburi dish that features tempura served over rice. The tenkasu can be sprinkled on top to enhance the texture and flavor, giving the dish an added dimension. Similarly, tenkasu can be mixed into onigiri rice balls for a unique twist on the traditional snack.
6. Okonomiyaki-Style Rice
For a fusion dish, tenkasu can be mixed into fried rice to replicate the crunchy, savory flavor found in okonomiyaki. Simply mix tenkasu with your choice of rice, vegetables, and seasonings, and stir-fry everything together for a satisfying meal that packs a punch of texture.
7. Salads and Soups
Tenkasu can also be sprinkled over salads or added to soups for an extra crunch. The crispy texture pairs well with fresh vegetables, tofu, or even miso soup, giving the dish a new layer of texture and flavor.
Making Tenkasu at Home
While tenkasu can be purchased at many Japanese grocery stores or online, it’s relatively simple to make at home. If you’re a fan of tempura, you likely already have the necessary ingredients on hand. Here’s a simple guide on how to make tenkasu at home:
Ingredients:
- 1/2 cup all-purpose flour
- 1/4 cup cornstarch
- 1/2 cup cold water
- A pinch of salt
- 1 egg (optional, for extra crispiness)
Instructions:
- In a mixing bowl, combine the flour, cornstarch, and salt.
- Add the cold water to the dry ingredients and stir until you form a batter. You want the batter to be thin and slightly runny, so don’t worry if it seems a little watery.
- If you want an extra crispy result, you can add a beaten egg to the batter, but this is optional.
- Heat oil in a deep fryer or a pot over medium-high heat. The oil should be hot enough to fry the batter, around 350°F (175°C).
- Drop small spoonfuls of the batter into the hot oil. The batter should immediately sizzle and form crispy bits. Fry until golden and crisp, then remove from the oil and drain on paper towels.
- Allow the tenkasu to cool, and it’s ready to use in your dishes!
Storing Tenkasu
Tenkasu can be stored for later use if you have leftovers. To keep the crispy bits fresh, store them in an airtight container at room temperature for up to a week. If you want to store them for a longer period, you can place them in the freezer. Just make sure to thaw them before using them in your dishes.
Conclusion
Tenkasu is a versatile and delicious ingredient that adds texture, flavor, and a touch of crispiness to a variety of Japanese dishes. Whether you’re making okonomiyaki, takoyaki, or a bowl of noodles, incorporating tenkasu into your recipes can elevate the dish to new heights.
