📝 About This Recipe

A beloved staple of Japanese home cooking and izakaya menus, Renkon no Hasami-age features a savory ground meat filling sandwiched between two slices of earthy, crunchy lotus root. When deep-fried to perfection, the lotus root develops a nutty sweetness that perfectly complements the juicy ginger-scented pork interior. This dish offers a spectacular play on textures—the 'snap' of the root against the tender meat—making it a sophisticated yet comforting addition to any Japanese feast.

🥗 Ingredients

The Lotus Root

  • 10-12 inches Lotus Root (Renkon) (about 400g, peeled and sliced into 1/4 inch rounds)
  • 1 tablespoon Rice Vinegar (for soaking water to prevent discoloration)
  • 3 tablespoons Potato Starch (Katakuriko) (for dusting the slices)

The Savory Filling

  • 250 grams Ground Pork (can substitute with ground chicken)
  • 2 pieces Shiitake Mushrooms (finely minced)
  • 2 stalks Green Onions (finely chopped)
  • 1 teaspoon Fresh Ginger (grated)
  • 1 teaspoon Soy Sauce
  • 1 teaspoon Sake
  • 1/2 teaspoon Sesame Oil
  • 1/4 teaspoon Salt and Black Pepper (to taste)
  • 1 tablespoon Potato Starch (Katakuriko) (to bind the meat)

The Frying Batter & Oil

  • 1/2 cup All-purpose Flour
  • 2 tablespoons Potato Starch (for extra crispness)
  • 1/2 cup Ice Cold Water (crucial for a light batter)
  • 3 cups Neutral Oil (vegetable, canola, or grapeseed for frying)

👨‍🍳 Instructions

  1. 1

    Peel the lotus root and cut it into rounds approximately 1/4 inch (5-6mm) thick. You should aim for an even number of slices.

  2. 2

    Immediately place the slices in a bowl of water mixed with 1 tablespoon of rice vinegar. Soak for 10 minutes to remove bitterness and prevent the root from turning brown.

  3. 3

    In a medium mixing bowl, combine the ground pork, minced shiitake, green onions, grated ginger, soy sauce, sake, sesame oil, salt, pepper, and 1 tablespoon of potato starch.

  4. 4

    Knead the meat mixture vigorously with your hand until it becomes pale and tacky/sticky. This ensures the filling won't fall out during frying.

  5. 5

    Drain the lotus root slices and pat them completely dry with paper towels. Moisture is the enemy of a crispy finish!

  6. 6

    Lay the slices out and lightly dust one side of each slice with potato starch using a small sieve. This acts as 'glue' for the meat.

  7. 7

    Place a small mound of meat (about 1-1.5 tablespoons) onto the starched side of one slice. Top with another slice, starched side down.

  8. 8

    Gently press the 'sandwich' together so the meat fills the decorative holes of the lotus root. Smooth the edges with your finger.

  9. 9

    Heat 2-3 inches of oil in a heavy-bottomed pot or wok to 340°F (170°C).

  10. 10

    Whisk the batter ingredients (flour, potato starch, and ice water) together briefly. Do not overmix; a few lumps are perfectly fine.

  11. 11

    Dip each lotus root sandwich into the batter to coat lightly, then carefully slide into the hot oil. Do not overcrowd the pot.

  12. 12

    Fry for 3-4 minutes per side, turning once, until the lotus root is golden brown and the meat is cooked through.

  13. 13

    Transfer to a wire rack or paper-towel-lined plate to drain for 2 minutes before serving.

💡 Chef's Tips

Ensure the lotus root is bone-dry before dusting with starch, otherwise the coating will peel off. Use ice-cold water for the batter to prevent gluten development, resulting in a much crispier shell. If you don't have potato starch, cornstarch is a suitable 1:1 substitute for the dusting and the batter. Pressing the meat into the holes of the renkon is key—it creates a mechanical lock that keeps the sandwich together. For a lighter version, you can pan-fry these with a lid on instead of deep-frying, though you lose the signature crunch.

🍽️ Serving Suggestions

Serve with a small dish of 'Karashi' (Japanese hot mustard) and soy sauce for dipping. A side of shredded green cabbage provides a refreshing, crunchy contrast to the fried root. Pairs beautifully with a chilled Japanese lager or a dry, crisp Sake. Serve as part of a traditional teishoku meal with miso soup and steamed white rice. Sprinkle with a little Shichimi Togarashi (seven-spice powder) for a spicy kick.
