Japanese Tempura Rice Bowl (Tendon)
Master the art of the perfect Japanese Tempura Rice Bowl with this guide to achieving light, crispy tempura and a savory, umami-rich sauce over steamed rice.
Tendon, or tempura donburi, is a beloved Japanese comfort dish that celebrates the harmony between crispy, golden-fried textures and steamed white rice. The key lies in the batter, which uses ice water to create a delicate, lace-like crust, and a perfectly balanced dashi-based sauce that ties the savory shrimp and vegetables together. This recipe brings the authentic street-food experience of a classic Japanese tempura shop into your own home.
Ingredients
- 4 bamboo shrimp
- 1 lotus root
- 4 shiitake mushrooms
- 1 eggplant
- 1 cup tempura flour
- 1 cup ice water
- 200 ml bonito broth
- 50 ml dark soy sauce
- 40 ml mirin
- 500 ml vegetable oil for frying
- to taste dry flour for coating
- 2 cups steamed white rice
Instructions
- 1Prepare the Tempura Batter

In a ceramic bowl, mix ready-made tempura flour with ice water. Whisk together until the batter reaches the consistency of thin yogurt, ensuring it is smooth and well-combined.
Tip: Using ice water is the secret to achieving an extremely crispy texture for your tempura. - 2Prepare the Bamboo Shrimp

Take the bamboo shrimp and remove the heads. Carefully peel the shell off the body, making sure to keep the tail intact for a better presentation. Trim the end of the tail into a swallowtail shape.
Tip: Trimming the tail into a swallowtail shape adds a professional touch to your tempura shrimp. - 3Straighten the Shrimp

After peeling, make shallow cuts across the belly of the shrimp to break the tendons. Gently press down on the shrimp meat to straighten it out, allowing the shrimp to become longer and more uniform for frying.
Tip: Breaking the tendons prevents the shrimp from curling up during the frying process. - 4Prepare the Tempura Sauce

In a pot, combine 200ml of bonito broth, 50ml of dark soy sauce, and 40ml of mirin. Bring the mixture to a boil to simmer, creating a flavorful dipping sauce for your tempura.
Tip: The combination of bonito broth, soy sauce, and mirin provides the classic savory-sweet profile of tempura sauce. - 5Coat Ingredients with Flour

Before frying, lightly dust all your ingredients—the prepared shrimp, scored shiitake mushrooms, sliced lotus root, and fanned eggplant—with a thin, even layer of dry flour.
Tip: A thin layer of dry flour helps the batter adhere better to the ingredients, ensuring a crispier crust. - 6Deep Fry the Tempura

Heat oil to 170 degrees Celsius. Dip the floured shrimp into the prepared batter and lower them into the hot oil. As you drop them in, gently shake the shrimp tail to create beautiful, crispy flakes in the oil.
Tip: Maintain the oil temperature at 170 degrees Celsius to ensure the shrimp is perfectly cooked and crispy without burning. - 7Fry the tempura vegetables

Carefully place the battered vegetables, including shiitake mushrooms, eggplant, and lotus root, into the hot oil. Ensure they are not crowded to maintain the oil temperature and fry until they are golden and crispy. Use a skimmer to remove them once cooked to your preference.
Tip: Keep the batter thin for vegetables to ensure they remain crispy rather than greasy. Fry in small batches to keep the oil temperature stable. - 8Assemble the tempura rice bowl

Arrange the freshly fried shrimp and vegetables neatly over a serving bowl filled with hot steamed rice. Finish by drizzling the prepared warm tempura sauce generously over the top of the crispy tempura.
Tip: Serve immediately while the tempura is still hot and crispy for the best texture contrast with the rice.
