Ingredients

Tempura Dipping Sauce

  • ¾ cup chicken broth
  • 3 Tablespoons soy sauce
  • 2 Tablespoons mirin
  • 2 teaspoons sugar granulated or brown sugar

Vegetables (about 24 pieces)

  • sweet potato peeled and sliced into ¼-inch discs
  • broccoli florets
  • asparagus
  • onion sliced into wedges
  • Japanese eggplant sliced into discs
  • oyster mushrooms
  • bell pepper strips

Tempura Batter

  • 1 egg
  • 1 cup all-purpose flour
  • 1 cup ice water
  • Vegetable or canola oil for frying (about 4 cups)

Instructions

Tempura Sauce

  • Make the tempura sauce by combining the broth, soy sauce, mirin, and sugar in a small saucepan over medium heat. Bring to a boil and simmer for 3-4 minutes until the sugar is dissolved. Cool to room temperature.

Prepare the Vegetables

  • If using sweet potatoes, peel and slice, then soak them in a bowl filled with cold water for 15 minutes to remove some of the starch before battering and frying.
  • Slice any vegetables as needed. If the broccoli florets are particularly large, you may want to cut them in half.

Make the Tempura Batter

  • Heat 2 inches of oil in a cast iron skillet or dutch oven over medium-high heat until it reaches 325-350 degrees F. It helps to have a thermometer handy to monitor the oil temperature.
  • Combine 1 cup of ice with 1 cup of water in a bowl and let this sit for a minute or so until the water is very cold. Measure your water from this to get 1 full cup for use in the recipe.
  • Add the flour to a large bowl. Beat the egg in another bowl, then add the egg and cold water to the flour. Stir in a figure-8 motion using chopsticks to gently combine the ingredients into a batter. It's okay if there are some lumps. Keep the batter cold by sticking it in the fridge when you aren't using it. Or stick the bowl of tempura batter in a larger bowl filled with an ice water bath to keep the batter completely cold.
  • Dry any veggies before dipping, especially the sweet potatoes, by patting them with paper towels so the batter will stick.
  • Dip each vegetable in the batter, then shake off excess and add them to the hot oil. Fry the root vegetables like sweet potatoes first since they take a little bit longer. Don't over crowd the pan or the oil temperature will drop quite a bit.
  • Fry the sweet potatoes for 3-4 minutes, flipping halfway through. For other vegetables like broccoli, onion, and bell pepper, they will only need to fry for 1-2 minutes typically.
  • Transfer the vegetable tempura to a wire rack over a baking sheet as they finish so they can drain without becoming soggy on paper towels. Sprinkle with salt and pepper, if desired, to season. Serve with dipping sauce.
