What You'll Need
Instructions
Add one egg white and 1 cup of potato starch to the marinated meat, along with a little rice flour or frying powder you have at home, and knead well so the powders coat the meat thoroughly.
Pour cooking oil into a pan and turn on the heat to let it reach the frying temperature.
When a piece of batter dropped into the oil hits the bottom and immediately rises, add the battered pork and fry.
Remove the golden-brown fried meat, and fry it once more to make it even crispier.
In a pan with 1/2 tbsp of cooking oil, stir-fry the onion, garlic, and ginger lightly to release their aroma.
Add about 1/2 cup of water (paper cup size) to the pan, then add 1 tbsp of Jin-ganjang, 3 tbsp of sugar, and 3 units of vinegar.
Add 1/3 tbsp of chicken stock and bring to a boil.
Gradually add a water-starch mixture (water mixed with starch) to the sauce, stirring until it thickens to complete the Tangsuyuk sauce.
