Tendon, or Tempura Donburi, is a beloved Japanese comfort food that crowns a simple bowl of steamed rice with delicately fried, crispy tempura. The secret to its signature crunch lies in using icy cold water and the technique of scattering tiny batter drops into the hot oil. Finished with a drizzle of savory sauce, this dish brings the authentic taste of a Japanese diner straight to your kitchen.

Ingredients

Instructions

  1. 1Prepare the tempura batter
    A bowl containing egg yolks, flour, cornstarch, and water, being mixed into a smooth tempura batter.

    In a glass bowl, whisk together two egg yolks, 50 grams of cornstarch, 100 grams of low-gluten flour, and 150 milliliters of cold water. Mix until you achieve a smooth, slightly thick consistency to ensure a perfect coating.

    Tip: Using cold water is crucial for a light, crispy tempura batter.
  2. 2Create crispy bits
    Crispy bits of batter frying in hot oil creating a golden crunchy texture.

    Heat oil to 175 degrees Celsius. Use your fingers to sprinkle small droplets of the prepared batter into the hot oil. These will fry into tiny crispy bits which will later be used to coat your tempura for extra texture.

    Tip: This technique creates the signature crunchy clothing for your tempura.
  3. 3Prepare the shrimp

    Peel and devein the large shrimp. Carefully use a knife to make a shallow cut along the back to remove the vein, which helps the shrimp stay straight during frying and ensures it is clean.

    Tip: Ensure the shrimp is completely dry after washing to help the batter stick better.
  4. 4Coat the shrimp

    Dip the prepared shrimp into the tempura batter, then immediately press or roll it in the crispy bits you fried earlier. This double-layer method adds a wonderful crunch to your tempura shrimp.

    Tip: Work quickly to ensure the batter doesnt slide off before it hits the oil.
  5. 5Fry the tempura shrimp

    Carefully place the fully coated shrimp into the hot oil at 175 degrees Celsius. Use chopsticks to hold the shrimp for a moment as they enter the oil to help them set their shape. Fry until the batter is golden brown and crispy then remove from the oil and drain.

    Tip: Holding the shrimp for a few seconds with chopsticks prevents them from curling too much and helps maintain a straight appealing shape.
  6. 6Assemble and sauce the bowl

    Once all your tempura pieces are fried, arrange them neatly over a bowl of warm, steamed rice. Finish the dish by drizzling a generous spoonful of savory tempura sauce over the top to bring all the flavors together.

    Tip: Adding the sauce right before serving ensures the tempura stays crispy while absorbing just enough flavor.

Frequently Asked Questions

Soggy tempura usually happens if the water wasnt cold enough, the batter was overmixed (which develops gluten), or the frying oil temperature dropped too low when adding the ingredients.
Yes. Let the oil cool completely, strain it through a fine-mesh sieve or coffee filter to remove the crispy bits, and store it in a cool, dark place. Use it for frying within a few weeks.
Low-gluten flour, such as cake flour, is ideal because it prevents the batter from becoming tough and chewy, resulting in a lighter, crispier coating.
