Tangsuyuk is Korean style sweet and sour pork. Well known as Korean Chinese food.



For the Pork

  • 1 cup potato starch
  • 1 1/2 lb pork loin, cut into 2-inch long 1/4-inch thin pieces
  • 1 tbsp soy sauce
  • 1 tbsp shaoxing wine
  • pinch of black or white pepper
  • 1/2 egg, beaten
  • 2 tbsp vegetable or avocado oil
  • frying oil

For the Sauce

  • 1 tsp cooking oil
  • 1/4 small sweet onion, 1-inch cube
  • 5 to 6 wood ear mushrooms, cut into bite size
  • 1/2 red bell, cut into 1-inch cube
  • 1/2 Persian cucumber, sliced
  • 3/4 cup chicken stock
  • 1/4 pineapple chunks in juice
  • 1/2 cup sugar
  • 1/4 cup white vinegar
  • 1 tbsp ketchup
  • fresh juice from 1/2 lemon
  • pinch of salt or 1 tsp soy sauce, optional
  • 1 tbsp starch, mixed with equal amount of cold water


  1. In a mixing bowl, combine potato starch and enough water to cover the potato starch, about 1-inch above. Mix well and let it sit at 5 hours or over night. When the water and starch separated completely, the water should ver very clean and starch is sink down on the bottom of the bowl. Very carefully, pour out only the water and keep the soaked starch for batter.
  2. In a large mixing bowl, combine pork, soy sauce, shaoxing wine and pepper. Marinate for 10 minutes.
  3. Preheat frying oil to 350°F
Using a spoon, break down the soaked and harden starch. Add beaten egg and oil then mix well. The texture of the batter is like condensed milk.
  4. Go ahead and combine the batter and the marinated pork. Mix well with your hand. Carefully drop one piece of pork at a time into 350°F preheated frying oil. Make sure the pork doesn’t stick to each others too much and not crowed the pot. Do 2 to 3 batches as you needed. Fry the pork about 2 to 3 minutes or longer if your pork pieces are bigger and thicker, don’t mind about the white/pair yellow color at this moment.
  5. Take out the pork and place on a cooling rack lined baking pan. Repeat with rest of the pork and let them cool completely before the second fry.
  6. Meanwhile waiting on the pork to cool down, let’s make the sauce. 
Heat a wok over high heat, add cooking oil, onion, red bell pepper, cucumber and wood ear mushrooms. Stir fry about 1 minute and add pineapple chunks with juice, chicken stock sugar, vinegar, lemon juice and ketchup. Stir everything together and bring it to boil. Add 1 tsp of soy sauce or pinch of salt to your taste.
  7. When the sauce is boiling, add the starch and water mixture while stirring the sauce. Keep it warm.
  8. Increase oil temp to 375°F
Second fry the cooled down pork until nice golden brown, about 2 minutes. Remove pork pieces from the oil and place on the cooling rack lined baking pan.
  9. You can serve the pork and the sauce sparely and just dip the pork in the sauce as you go, I recommend this if you like to enjoy crispy pork until the end. Or you can pour the sauce on top of the pork, which is very classic way to serve it. Enjoy!
