Ingredients
  

  • 1 medium sweet potato ¼ inch slices
  • ¾ cup all purpose flour divided
  • ½ cup cold water
  • oil for frying
  • salt to taste

Tempura Dipping Sauce

  • ¼ cup water
  • heaping ¼ teaspoon hondashi powder
  • 1 tablespoon soy sauce
  • 2 teaspoons mirin
  • ½ teaspoon sugar

Instructions
 

  • In a small saucepan, bring dipping sauce ingredients to a boil and mix until the sugar is dissolved. Set aside.
  • In a skillet, heat 1 inch of oil on medium high heat to 375°F.
  • While the oil is heating up, prepare two bowls. One with ¼ cup of flour and another with ½ cup of flour mixed with ½ cup of cold water. The tempura batter should be the consistency of thin pancake batter and small clumps are fine. Add 1 tablespoon of water at a time if needed.
  • Dip slices of sweet potato into the flour then into the batter. Let the excess batter drip back into the bowl.
  • Fry for 2-3 minutes on each side then drain on a wire rack and season with salt. Repeat with remaining sweet potatoes.
  • Serve the sweet potato tempura immediately with the dipping sauce.

Notes

  • Use cold water. We want to minimize gluten development in the batter to ensure a light and crispy coating.
  • Fry in batches. Don't overcrowd the pan or the temperature of the oil will drop too low resulting in a less crispy coating.
  • You can also dip these in soy sauce or spicy mayo.
