Batter

A light batter is made of iced water, eggs,^[1] and soft wheat flour (cake,^[2] pastry^[3] or all-purpose flour^[1]). Sometimes baking soda^[4] or baking powder is added to make the fritter light.^[4] Using sparkling water in place of plain water^[5] has a similar effect. 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 a unique fluffy and crisp tempura structure when cooked. The batter is often kept cold by adding ice or placing the bowl inside a larger bowl with ice. Overmixing the batter will activate wheat gluten, which causes the flour mixture to become soft and dough-like when fried.

Specially formulated tempura flour is available in supermarkets. This is generally light (low-gluten) flour and occasionally contains leaveners such as baking powder.^[6]

Tempura does not use breadcrumbs (panko) in the coating.^[7] Deep-fried foods that are coated with breadcrumbs are called furai,^[8] Japanese-invented Western-style deep-fried foods, such as tonkatsu or ebi furai (fried prawn).^[8]

No seasonings or salt is added to the batter, or the ingredients,^[1] except for some recipes recommending rinsing seafood in salt water before preparation.^[9]

Frying

Frying tempura

Thin slices or strips of vegetables or seafood are dipped in the batter, then briefly deep-fried in hot oil.^[1] Vegetable oil^[10] or canola oil are most common; however, tempura was traditionally cooked using sesame oil.^[11] Many specialty shops still use sesame oil or tea seed oil, and it is thought certain compounds in these oils help to produce light, crispier batter.

The finished fry is pale whiteish, thin and fluffy,^[12] yet crunchy.^[13]

The bits of batter (known as tenkasu) are scooped out between batches of tempura so they do not burn and leave a bad flavor in the oil.^[1] A small mesh scoop (Ami jakushi) is used for this purpose. Tenkasu are often reserved as ingredients in other dishes or as a topping.

Serving and presentation

Tentsuyu is the most common sauce consumed with tempura.

Cooked pieces of tempura are either eaten with dipping sauce, salted without sauce, or used to assemble other dishes. Tempura is commonly served with grated daikon and eaten hot immediately after frying. In Japan, it is often found in bowls of soba or udon soup in the form of shrimp, shiso leaf, or fritter. The most common sauce is tentsuyu sauce (roughly three parts dashi, one part mirin, and one part shōyu). Alternatively, skim tempura may be sprinkled with sea salt before eating. Mixtures of powdered green tea and salt or yuzu and salt are also used.^[15] Kakiage is a type of tempura made with mixed vegetable strips, such as onion, carrot, and burdock, and sometimes including shrimp or squid, which are deep fried as small round fritters.

Tempura is also used in combination with other foods. When served over soba (buckwheat noodles), it is called tempura soba^[16] or tensoba. Tempura is also served as a donburi dish where tempura shrimp and vegetables are served over steamed rice in a bowl (tendon) and on top of udon soup (tempura udon).

Origins

Earlier Japanese deep-fried food was either simply fried without breading or batter or fried with rice flour. However, toward the end of the 16th century, the technique of fritter-cooking with a batter of flour and eggs was acquired in Nagasaki by Portuguese missionaries. It was a way to fulfill the fasting and abstinence rules for Catholics surrounding the quarterly ember days (Spanish: Témporas).^[18] In those days, tempura was deep-fried in lard with a batter of flour, water, eggs, and salt; unlike today, it was eaten without dipping sauce.

In the early 17th century, around the Tokyo Bay area, tempura ingredients and preparation underwent a remarkable change as the yatai (food cart) culture gained popularity. Making the best use of fresh seafood while preserving its delicate taste, tempura used only flour, eggs, and water as ingredients, and the batter was not flavored. As the batter was mixed minimally in cold water, it avoided the dough-like stickiness caused by the activation of wheat gluten, resulting in the crispy texture, which is now characteristic of tempura. It became customary to dip tempura quickly in a sauce mixed with grated daikon just before eating it.

Today in Japan, the mainstream of tempura recipes originate from "Tokyo style" (also known as Edo style) tempura, invented at the food stalls along the riverside fish market in the Edo period. The main reason tempura became popular was the abundance of seafood. In addition, as oil extraction techniques advanced, cooking oil became cheaper. Serving deep-fried food indoors was prohibited during Edo because tempura oil was a fire hazard in Japanese buildings, which were made of paper and wood. Therefore, tempura gained popularity as fast food eaten at outdoor food stalls. It was skewered and eaten with a dipping sauce. Tempura is considered one of "the Edo Delicacies" along with soba (buckwheat noodles) and sushi, which were also food stall take-outs.

The modern tempura recipe was first published in 1671 in the cookbook called "料理献立抄". After the Meiji period, tempura was no longer considered a fast food item but developed as a high-class cuisine.

Etymology

Look up tempura in Wiktionary, the free dictionary.

The word "tempura", or the technique of dipping fish and vegetables into a batter and frying them, comes from the word tempora, a Latin word meaning "times", "time period" used by both Spanish and Portuguese missionaries to refer to the Lenten period or Ember Days (ad tempora quadragesima), Fridays, and other Christian holy days. Ember Days, or quatuor anni tempora in Latin, refer to holy days when Catholics avoid red meat and eat fish or vegetables instead.^[19][20] The idea that the word "tempura" may have been derived from the Portuguese noun tempero, meaning a condiment or seasoning of any kind, or from the verb temperar, meaning "to season" is also possible as the Japanese language could easily have assumed the word tempero as is, without changing any vowels as the Portuguese pronunciation, in this case, is similar to the Japanese.^[21] There is still today a dish in Portugal very similar to tempura called peixinhos da horta, "garden fishes", which consists of green beans dipped in a batter and fried.

The term "tempura" is thought to have gained popularity in southern Japan; it became widely used to refer to any food prepared using hot oil, including some already existing Japanese foods. Today, particularly in western Japan, the word "tempura" is also commonly used to refer to satsuma-age, fried surimi fish cake which is made without batter.^[22][23]

Japan

In Japan, restaurants specializing in tempura are called tenpura-ya. Many restaurants offer tempura as part of a set meal or a bento (lunch box), and it is also a popular ingredient in take-out or convenience store bento boxes. The ingredients and styles of cooking and serving tempura vary greatly throughout the country, with importance placed on using fresh, seasonal ingredients.

Outside Japan

Outside Japan (as well as recently in Japan), there are many nontraditional and fusion uses of tempura. Chefs all over the world include tempura dishes on their menus, and a wide variety of different batters and ingredients are used, including nontraditional broccoli, zucchini, asparagus and chuchu. More unusual ingredients may include nori slices, dry fruit such as bananas, and ice cream (tempura-based fried ice cream). American restaurants are known to serve tempura in the form of various types of meat, particularly chicken and cheeses, usually mozzarella. A variation is to use panko (breadcrumbs), which results in a crisper consistency than tempura batter, although in Japan this would be classified as a furai dish. Tempura (particularly shrimp) is often used as a filling in makizushi. A more recent variation of tempura sushi has entire pieces of sushi dipped in batter and tempura-fried.

In Bangladesh, the blossoms of pumpkins or marrows are often deep-fried with a gram of rice flour spice mix, creating a Bengali-style tempura known as kumro ful bhaja.
