Sweet Potato Tempura Ingredients
- Sweet Potato: Choose a medium to large sweet potato. There's no need to peel it, but be sure to scrub the outside and dry it before slicing.
- Sparkling Water: If you want your tempura to come out extra light and crispy, the secret is to add ice to your sparkling water. Ice cold water yields fluffy and light tempura.
- Rice Flour: Rice flour is the traditional flour used in tempura batter, and I think it yields the best results. However, if you want to replace it with another flour, the recipe will still work.
- All Purpose Flour: A combination of rice flour and all purpose flour give the tempura batter just the right texture. If you want gluten free sweet potato tempura, it's ok to swap the all purpose flour for more rice flour.
- Baking Powder: Baking powder helps the tempura puff up, making it light and fluffy.
- Salt: Salt naturally enhances the flavor of all the other ingredients.
- Vegetable Oil: Canola oil is my top choice for deep frying. It has a high smoke point and a neutral flavor. Sunflower oil is also a good choice.

Dipping Sauce Ingredients
- Tamari or Soy Sauce: I like to use tamari sauce, but soy sauce works equally well.
- Sriracha Sauce: Add a little spice with a chili garlic sauce. Sambal Oelek also works here. Feel free to omit it if you're making this recipe for children, or simply prefer a less spicy dipping sauce.
- Mirin: Mirin often gets confused with rice wine vinegar. The difference is that mirin adds a sweeter flavor. However, rice wine vinegar will still work, if that's what you have on hand.
- Maple Syrup: ย Maple syrupย adds a nice earthy sweet flavor that works perfectly in this recipe, plus it makes your sweet potato tempura dipping sauce refined sugar free.

Serving Suggestions

- Serve as with a batch of vegan sushi for a full Japanese inspired meal.

- Instead of slicing your sweet potato into rounds, slice them into sticks or wedges.
