A light batter is made of cold water and wheat flour. Eggs, baking soda or baking powder, starch, oil, and/or spices may also be added. Tempura batter is traditionally mixed in small batches using chopsticks for only a few seconds, leaving lumps in the mixture that, along with the cold batter temperature, result in the unique fluffy and crisp tempura structure when cooked. The batter is often kept cold by adding ice, or by placing the bowl inside a larger bowl with ice in it. Over-mixing the batter will result in production of wheat gluten, which causes the flour mixture to become chewy and dough-like when fried.
Specially formulated tempura flour is available in Japanese supermarkets. This is generally light (low-gluten) flour and occasionally contains leaveners such as baking powder.
Some varieties of tempura are dipped in a final coating, such as sesame seeds, before frying. Tempura generally does not use breadcrumbs in the coating. Generally fried foods which are dipped in breadcrumbs (panko) are considered to be furai (Japanese-invented faux western-style deep fried foods, such as tonkatsu or ebi Fried Prawn).
Thin slices or strips of vegetables or seafood are dipped in flour, then the batter, then briefly deep-fried in hot oil. Vegetable oil or canola oil are most common, however tempura was traditionally cooked using sesame oil. Many specialty shops still use sesame oil or tea seed oil, and it is thought that certain compounds in these oils help to produce light, crisp batter.
When cooking shellfish, squid, or hard-skinned watery vegetables such as bell pepper or eggplant, it is important to score the skin with a knife to prevent the ingredients from bursting during cooking. Failing to do so can lead to serious burns from splashing oil.
Oil temperature is generally between 160 and 180 degrees Celsius, depending on the ingredient. In order to preserve the natural flavour and texture of the ingredients, it is important not to overcook tempura. Cooking times range between a few seconds for delicate leaf vegetables, to several minutes for thick items or large kaki-age fritters.
It is important to scoop out the bits of batter (known as tenkasu) between batches of tempura, so they do not burn and leave a bad flavour in the oil. A small mesh scoop is used for this purpose. Tenkasu are often reserved as ingredients in other dishes or as a topping.
