Don-Gaseu (돈까쓰 or 돈가스) is a Korean dish which originated from the Japanese dish Tonaktsu. Don-Gaseu was brought to Korea in 1876 when the country gave an opportunity to foreign countries and opened their doors to the products and foods from Japan and the United States.
Back in the 1980s, only Western restaurants in Seoul offered the now popular and most common dish. The most popular one 'Italiano' in Jeong-Dong served the pork cutlet with a side of kimchi and "danmuji" (yellow pickled radish).
Don-Gaseu is a pork cutlet with a sauce made specifically for the dish with a side of vegetables and rice.
Some Korean shops usually have already prepared pork loin cutlets so it's easier to cook. It's coated in flour, eggs and finally panko breadcrumbs which is then double fried to achieve that perfect crust (in Korean cooking, you usually double fry any meat as opposed to a single fry). The sauce can be bought in store or home-made. You can find store bought sauce at your local Korean shop or you can purchase it at another Asian market. Korea's version of Tonkatsu is typically larger and thinner, however, in Japan it's smaller and thicker in size.
My personal favorite sauce:
Each country has its own spin on the Japanese style dish, but my favorite has to be Korea's approach and flavor. If you haven't tried Korean food yet or are looking for a new Korean dish to try, I highly recommend this one. It was the first Korean meal I've had, and I simply can't get enough of it!
“It's so delicious and exciting. [It's] what the cool kids want — spicy, funky, fermented, that whole spectrum of flavors.” - Anthony Bourdain on Korean dishes.
