In a large bowl, add the starch and pour water on top of it. Let it sit for an hour as the starch sinks to the bottom of the bowl. Don't mix it!
1 cup potato or corn starch, 1 cup water
Cut the meat into long strips, ~1-2 inches thick
10 oz pork loin
In a mixing bowl, add the pork and mix with salt, pepper, ginger, and msg (optional). Place it in the refrigerator while making the sauce.
1/2 tsp salt, 1/2 tsp black pepper, 1 tsp chopped ginger, 1/4 tsp MSG
Cut vegetables into 2-3" inches long
1 carrot, 1/4 onion, 1-2 cucumbers, 1/3 cup woodear mushrooms
Drain out the pineapples from the can. Save the liquid! Cut the pineapples if needed.
10 oz canned pineapple
In a medium sauce pan, combine water, sugar, soy sauce, apple cider vinegar, and juice of the canned pineapple. Cook it over medium-low and bring it to a boil
1 cup water, 3-4 tbsp sugar, 2 tbsp soy sauce, 2 tbsp apple cider vinegar, 10 oz canned pineapple
Add carrots, mushrooms, and onions. Cook on medium low for 1 minute.
Add cucumbers and pineapples. Cook for another 2 minutes, turn off the stove, and set it aside.
Slowly drain out the water from the starch. It's okay if some starch pours out... just not too much.
Add the egg white on the starch.
1 egg white
Take out the meat from the refrigerator and combine it with the egg white starch mixture. It's the easiest to do this step using clean hands.
Using a cast iron, metal pots, or a wok, heat up vegetable oil to 350 degrees farenhite. Don't leave the pot unattended!
3-4 cups Vegetable oil for frying
Using metal tongs or long chopsticks, carefully add 4-6 pieces of battered meat into the heated frying oil and cook until golden brown or for about 3 minutes The meat will stick to each other if all are added too much at once.
Remove from the oil and let it drain on a cookie rack or a large mesh strainer over paper towel. Repeat the previous step and this step until all pieces of meat are fried.
Reheat the oil to 350 degrees farenhite and double fry the meat all together for a crispier exterior for 2-3 minutes.
Remove from the oil and strain
Served the fried pork on a large plate and either pour the sweet and sour sauce over it or dip each piece of pork into the sauce.
