In a mixing bowl, combine flour and salt. Add butter and mix using fork or finger tips until pea size like. In a separate bowl, whisk vinegar, egg, and cold water. Pour into the flour mixture little by little and mix together using your hands until the mixture turns dough like. Make into a circular shape and cover with plastic wrapper. Allow to sit in the fridge for 1 hour. Make a golf ball size shape and flatten by using the palm of your hand. Using a rolling pin, roll each ball until it’s about 1/8 inch thick. Use a wide-mouth bowl as a pattern for a nice round shape about 4 inch diameter. Cut off the extra edges using a pizza cuter or knife. Set aside.
For filling: Heat cooking oil in pan. Saute onion and garlic. Add ground pork and saute until golden brown. Place in chopped carrots and potatoes. Stir and allow to cook for 10 minutes.
After 10 minutes, add the green peas, raisins, and potatoes. Season with soy sauce, pepper and salt. Stir and simmer, until the vegetables, are cooked. Allow to cool and set aside.
