Stages of cooking

  1. Make the tempura: Beat eggs in a large bowl until frothy. Stir in 3/4 cup plus 3 tablespoons ice water, 3/4 cup plus 1 tablespoon flour, and salt until just incorporated; batter should still be very lumpy.

  3. Dry sweet potato slices with paper towels. Dip three slices into batter, letting excess batter drip back into the bowl. Fry in the preheated oil until golden brown, about 2 minutes per side. Use a slotted spoon to transfer sweet potatoes to the wire rack. Repeat to dip and fry remaining sweet potatoes.

History of the Sweet Potato Tempura:

Tempura is a traditional Japanese dish made of battered and deep-fried seafood or vegetables. Originally, Portuguese traders and missionaries introduced a similar dish called "Peixinhos da horta" to Japan in the 16th century. However, Japanese chefs adapted the recipe to use local ingredients, such as sweet potato, and created a unique type of tempura.

Today, sweet potato tempura is a popular appetizer or snack in many Japanese restaurants and households, thanks to its crispy texture and sweet flavor.

Tips and Tricks for Sweet Potato Tempura Recipe:

  • Use cold water and keep the batter lumpy: To ensure a light and crispy batter, use very cold water and mix the ingredients just until they are combined. Small lumps in the batter will make the tempura even more crunchy.
  • Choose the right type of oil: Use a neutral oil with a high smoke point, such as canola or grapeseed oil, for deep-frying. Heating the oil to the right temperature is also crucial to achieve a golden-brown color and avoid sogginess.
  • Fry in small batches: Avoid overcrowding the fryer or pan by frying a few slices at a time. This will prevent the temperature of the oil from dropping and result in a more even cooking.
  • Drain excess oil: After frying, use a slotted spoon to transfer the sweet potato tempura onto a wire rack lined with paper towels. This will remove any excess oil and keep the tempura crisp.

Tips for presenting the dish:

  • Serve with dipping sauce: Mix rice wine and soy sauce to create a simple yet flavorful dipping sauce that pairs well with the sweet potato tempura. Alternatively, you can use other dipping sauces, such as honey mustard or Sriracha mayo.
  • Garnish with sesame seeds: Sprinkle a few toasted sesame seeds over the sweet potato tempura to add texture and flavor. Chopped scallions or cilantro are other good options for garnish.
  • Serve hot and fresh: Sweet potato tempura tastes best when it is still warm and crisp. Serve immediately after frying and avoid reheating in the microwave or oven, as it can make the tempura soggy.
