Ingredients

Instructions

  1. Step 1: Heat 2 cups vegetable oil in a deep fryer or large pot to 350°F (175°C). In a bowl, whisk together tempura batter, ensuring no lumps remain.
  2. Step 2: Dip 1 cup lotus root into the batter, allowing excess to drip off, then carefully lower into the hot oil. Fry for 3-4 minutes until golden and crispy, turning once. Transfer to a paper towel-lined plate.
  3. Step 3: While the lotus root fries, steam sweet potato cubes for 15 minutes until tender. In a blender, combine steamed sweet potato, 1 tbsp soy sauce, and 1 tbsp grated ginger. Blend until smooth, adding 1-2 tbsp water if needed for a creamy consistency.
  4. Step 4: Serve the tempura alongside the sweet potato puree, garnished with a drizzle of soy sauce and a sprinkle of fried shallots.

How do I scale Crispy Lotus Root Tempura with Sweet Potato Puree for a different number of people?
