Ingredients

  • ¾ cup all-purpose flour
  • ½ cup cornstarch
  • 1 egg, beaten
  • 1 cup ice cold club soda
  • ½ teaspoon salt + more for seasoning
  • vegetable oil for frying
  • 1 large sweet potato, peeled and sliced into ⅛ inch rounds
  • dipping sauce like Tentsuyu

Instructions

  • To make the batter, mix together the flour, cornstarch, egg, club soda and salt in a bowl. The batter should be lumpy.
  • Heat pot of oil at least 3" deep to 350°F.
  • Make sure the sliced sweet potato rounds are dry. Dip 2-3 slices in the batter and let any excess drip back into the bowl before adding to the hot oil. Fry for 2 minutes per side or until golden brown.
  • Remove with a slotted spoon or spider strainer and place on a paper towel-lined plate to absorb any excess oil. Sprinkle with salt and repeat with the remaining sweet potatoes. Serve with dipping sauce.

Notes

  • Slice the sweet potatoes thinly and uniformly to ensure even cooking. Use a mandoline slicer if you have one for consistent results.
  • Keep the oil temperature consistent throughout the frying process. Fluctuating temperatures can lead to uneven cooking and less crispiness. Adjust the heat as needed to maintain the desired frying temperature.
  • Fry the sweet potatoes in small batches to avoid overcrowding, which can lead to uneven frying.
  • After frying, place the sweet potatoes on paper towels or a wire rack to drain excess oil.
  • Sprinkle a pinch of salt or your preferred seasonings on the tempura as soon as it's out of the oil while it's still hot to enhance flavor.
