Tansuyuk is a Chinese dish that is deep fried crispy pork drenched in sweet and sour sauce and it has become a popular staple in Korea.   The dish was introduced from the community of Chinese immigrants in Korea. Predominantly in Incheon where so many Chinese immigrants lived. As it popularity rose, the evolution of the dish has changed as certain ingredients were replaced. The type of starch that is used in Korean iteration of this dish is potato starch instead of glutinous rice flour. The use of potato starch gives the dish a much more crunchy texture without sacrificing the color due to the high boiling temperature.


Tangsuyuk is primarily prepared with pork, but in some instances, it can be made with beef. In this recipe, pork will be used. Before you start frying it is important to prepare all your ingredients from the start. This will include marinating the pork loin with ginger, black pepper, salt, cooking wine, and sugar for at least and 30 minutes. The longer the better. 

For the batter, you will need a type of starch and it can be any kind of starch, but I found that there was a particular reason to why potato starch is used. Potato starch in comparison to other type so starches has a higher boiling point, so you can achieve a satisfying level of crispiness without affecting the color of it. The starch will have to be submerged in water for at least and hour. This will give the dish that iconic chewy yet crispy texture.

Sweet and Sour Sauce

The sweet and sour sauce is a must when it comes to Tangsuyuk. Its thick and sticky texture is a stark contrast to the chew and crunchy texture of the pork batter. It is made from mixing up water, sugar, vinegar, soy sauce, oyster sauce, carrot, cucumber, onion, woodear mushroom, and a slurry mix. The sauce is is perfect for dipping or pouring it all  over the dish. It is completely up to preference.
