Ingredients

  • 1 Japanese Sweet Potato
  • Oil for deep-frying

Batter

  • 200 ml Cold water
  • 100 g Cake flour
  • ½ teaspoon Baking powder

Tempura Sauce

  • 600 ml Mentsuyu Dilute with water according to the bottle instructions.
  • 1 inch Daikon radish

Instructions

  • Cut sweet potato: Cut sweet potato into thin slices.
  • Prepare a pan: Put oil about 2 cm (1 inch) high in a pan and heat it to 170C (335F).
  • Make the batter: Add cold water to a bowl, sift the flour and baking powder with a strainer, and mix.
  • Deep-fry: Dip the sweet potato in batter, put them in the pan, and deep-fry until cooked (about a couple of minutes). Place them on a cooling rack to drip excess oil.
  • Make Tentsuyu: Grate the daikon radish (daikon oroshi). Dilute mentsuyu (noodle soup) with water according to the bottle instructions and add daikon oroshi.

Notes

  • Equipment: I use an Iron frying pan 22 cm/9 inches. Any deep pot is ok.
  • Variations: See "Best vegetables for tempura" for more variations.
  • Do not mix the batter until smooth. If you mix too much, the gluten will be formed, and your tempura will be heavy and chewy. 
  • Do not fry too many at once to keep the oil temperature consistent.
  • Do not throw the leftover batter. You can make tenkasu (tempura flakes) and use it as a topping on noodles or rice bowls.
