Ingredients
Scale
Batter Ingredients
- 3/4 cup cake flour, sifted
- 1/4 cup cornstarch
- 1 large egg, lightly beaten
- 1 cup ice-cold sparkling water
Main Ingredients
- Vegetables and seafood of your choice (e.g., sweet potato slices, shrimp, shiitake mushrooms)
Frying
- Vegetable oil for deep frying (preferably canola or sunflower oil)
- Salt to taste, for finishing
Instructions
- Prepare the ingredients: Pat the vegetables and seafood dry thoroughly with paper towels to remove any surface moisture. This step is crucial because excess water can cause the batter to become soggy and reduce crispiness during frying.
- Mix the batter: In a chilled bowl, combine the sifted cake flour and cornstarch evenly. Add the lightly beaten egg, then gradually pour in the ice-cold sparkling water. Stir gently with chopsticks or a fork just until combined; lumps are acceptable. Avoid overmixing to prevent gluten formation, which can make the batter tough.
- Heat the oil: Using a deep-fryer or a heavy-bottomed pot, heat the vegetable oil to a consistent temperature of 350°F (175°C). Use a cooking thermometer to monitor and maintain this heat level precisely. Proper temperature is essential to ensure the batter crisps up quickly without absorbing excess oil or burning.
- Coat and fry: Dip each prepared vegetable and seafood piece into the batter, allowing excess to drip off. Carefully lower the pieces into the hot oil in small batches to avoid overcrowding, which can drop the oil temperature. Fry for about 2-3 minutes until the tempura turns a pale golden color and attains a crispy texture. Gently stir if pieces stick together.
- Drain and cool: Remove the fried tempura using a slotted spoon and place them on a wire rack set over paper towels to drain excess oil. Let the tempura cool slightly before serving; this cooling step helps steam escape and maintains the crispiness without sogginess.
Notes
- Using ice-cold sparkling water in the batter helps keep it light and airy because the carbonation adds bubbles that enhance crispiness.
- Avoid overmixing the batter to prevent developing gluten, which can make the tempura tough rather than crisp.
- Maintaining oil temperature precisely is key to achieving the perfect fry—too hot burns the batter and too cool makes it greasy.
- Use a wire rack to drain excess oil instead of paper towels alone to avoid steaming the tempura and losing crispness.
- Choose vegetables and seafood that fry well, such as sweet potatoes, shrimp, and mushrooms—cut vegetables thinly for even cooking.
