Tempura flour

Tempura flour is not just ordinary flour. It's a mixture created for one specific result: a crispy, airy coating around the product during deep frying. Its main difference from regular wheat flour is that it contains starch, often rice starch, and sometimes potato starch. It's this combination that creates that light, bubbly layer that is so valued in Japanese cuisine.

What's inside and how it works

Tempura flour typically contains wheat flour, rice flour, and starch. Some manufacturers add leavening agents or even dried egg. Starch is the key component. When you mix this flour with cold water and immediately dip it into hot oil, the starch quickly absorbs moisture and creates those signature air pockets. The result is not a dense crust, but a delicate, crispy coating that almost melts in your mouth.

Where and how to use

Tempura is not just vegetables. Of course, zucchini, eggplant, sweet pepper, and mushrooms in batter made from this flour turn out perfectly. But shrimp, fish, and even thin slices of cheese are also dipped in the batter. The main rule: mix the flour with ice-cold water right before frying, don't prepare the batter in advance. Lumps in the batter are not a mistake, but the norm. They create an even more interesting texture.

Practical tips when choosing

• Check the ingredients: there should be wheat flour and rice flour, starch. If you only see wheat flour — this is not quite right.
• Store in a dry place in a tightly sealed package. Flour absorbs moisture, and this causes it to lose its ability to create a crispy crust.
• If you don't have flour on hand, you can mix regular wheat flour with starch in a ratio of approximately 2:1, but the result will be slightly less airy.
• Oil temperature — 170–180 degrees. If the oil is colder, the flour will absorb it instead of creating a crust.

What to serve with

Tempura is delicious on its own, but truly shines with a light sauce. The classic option is a blend of soy sauce, mirin, and dashi. You can offer a spicy sauce made with mayonnaise, ketchup, and wasabi. Fresh lemon or lime also work well. The key is not to overdo it: the crispy coating should remain the star of the dish.
