# Tonkatsu

Tonkatsu (豚カツ, とんかつ or トンカツ, pronounced; "pork cutlet") is a Japanese dish that consists of a breaded, deep-fried pork cutlet. It involves coating slices of pork with panko (bread crumbs), and then frying them in oil. The two main types are fillet and loin. Tonkatsu is also the basis of other dishes such as katsu curry and katsudon.

## Etymology

The word tonkatsu is a combination of the Sino-Japanese word ton (豚) meaning "pig", and katsu (カツ), which is a shortened form of katsuretsu (カツレツ), an old transliteration of the English word "cutlet", which was in turn adopted from the French word côtelette.

## History

Tonkatsu originated in Japan during the Meiji Era in the late 19th century, a dish derived from a French dish known as côtelette de veau, a veal cutlet coated in breadcrumbs and fried in a pan with butter.
European katsuretsu (loanword/gairaigo for cutlet) was usually made with beef; the pork version was created in 1899 at a restaurant serving European-style foods named Rengatei in Tokyo, Japan. It is a type of yōshoku—Japanese versions of European cuisine invented in the late 19th and early 20th centuries—and was called katsuretsu or simply katsu.

## Preparation and serving

Either a pork fillet (ヒレ, hire) or pork loin (ロース, rōsu) cut may be used; the meat is usually salted, peppered, dredged lightly in flour, dipped into beaten egg and then coated with panko (bread crumbs) before being deep fried.
Tonkatsu is then sliced into bits and served, commonly with shredded cabbage. It is most commonly eaten with a thick Worcestershire-style sauce called tonkatsu sauce or simply sōsu (sauce), karashi (mustard), and perhaps a slice of lemon. It is usually served with rice, miso soup and tsukemono and eaten with chopsticks. It may also be served with ponzu and grated daikon instead of tonkatsu sauce.

## Variations

Tonkatsu is also popular as katsu curry, where it is served with Japanese curry, or as katsudon, simmered with egg and broth, then served on a big bowl of rice; there is also katsu rice, which is pork cutlet served on rice topped with demi-glace sauce. Another popular variation, katsu-sando or pork cutlet sandwich, is said to be originated from the Isen, a tonkatsu restaurant. In the 1930s, the manager of the Isen came up with the concept, then improved it by making the sandwich smaller so that its clientele of local geishas could enjoy it without wearing off their lipstick.
In Nagoya and surrounding areas, miso katsu, tonkatsu eaten with a hatchō miso-based sauce, is a speciality.
Variations on tonkatsu may be made by sandwiching an ingredient such as cheese or shiso leaf between the meat, and then breading and frying.
Variations of katsu other than pork:
* Chicken katsu (チキンカツ) or tori katsu (鶏カツ), which uses chicken instead, often appears in Hawaiian plate lunches.
* Menchi-katsu (メンチカツ) or minchi katsu (ミンチカツ mince katsu), is a minced meat patty, breaded and deep fried.
* Hamu katsu (ハムカツ ham katsu), a similar dish made from ham, is usually considered a budget alternative to tonkatsu.
* Gyū katsu (牛カツ beef katsu), also known as bīfu katsu, is popular in the Kansai region around Osaka and Kobe.
In general, breaded and deep-fried foods are called furai ("fry"), such as ebi-furai (fried prawn) and aji-furai (fried horse mackerel), but fried meat such as pork, beef and chicken is referred to as katsu (cutlet). Katsu and furai differ from tempura, which is not breaded but battered and typically fried in sesame oil.
In recent years, chicken katsu curry has become extremely popular in the United Kingdom, to the point that other varieties of Japanese curry and curry sauce are sometimes referred to as katsu erroneously.
