For Better Tempura, You Need Soda Water

For better tempura, soda water can be a transformative ingredient, thanks to its unique properties. The key to achieving the light and crispy texture that tempura is known for lies in the batter. Traditional tempura batter is made with a simple mixture of flour and water, but using soda water instead of regular water can elevate the end result. The carbonation in soda water introduces bubbles into the batter, which helps create a lighter, more airy texture when fried. This fizz not only contributes to the batter's crispness but also prevents it from absorbing too much oil during cooking, resulting in a less greasy finish. Additionally, the cold temperature of the soda water is crucial; it helps to keep the batter chilled, which is essential for creating a contrast between the cold batter and the hot oil, further enhancing the crispiness. Incorporating soda water into the batter is a simple yet effective technique that can bring out the best in tempura, ensuring that each piece remains delicate and crunchy. This method is particularly beneficial for home cooks seeking to replicate the lightness and texture of professionally made tempura, providing a delightful and satisfying dining experience.

Getting tempura batter to the right consistency

You can opt for club soda, sparkling water, or tonic water when making tempura, but keep in mind that they will each produce different results due to their varying mineral compositions. Tonic water contains quinine, which imparts a bitter flavor, while sparkling water is the most neutral of the three. The minerals in club soda lend a saltier taste, making it a great choice for frying. It may take some experimentation to find your preferred carbonated option, as each can alter the texture of the tempura.

Alternatively, you can skip the water altogether and use some inexpensive vodka. Its neutral flavor won’t overpower the tempura, and it effectively prevents gluten formation in the batter, resulting in a lighter, flakier crust. Whether you choose vodka or carbonated water, just be sure to keep it chilled before cooking.

Tempura batter is typically made by combining cold liquid and egg with wheat flour, but if you prefer a firmer fry, there are pre-made mixes available that include cornstarch and additional leavening agents. Kikkoman offers an extra crispy tempura batter mix on Amazon for about $6. Simply mix the ingredients with chopsticks, coat your food, and fry it in hot vegetable oil for delicious homemade tempura.
