First Mr. Yan, the chef, cut 7-8 liang of pork loin into bite-sized strips. I'm not sure what kind of measurement a "liang" is, so if any of my Chinese-speaking friends know, please leave a comment! This will give you a good idea of the size:
Next, cut the ends of 1 red pepper and 1 green pepper (both non-spicy), and remove the center and the seeds. Cut both peppers into about 1 1/2 inch triangles. Chop up 1 yellow into large pieces, and set the onion and peppers aside together.
Take one clove of garlic and one piece of ginger (same size as the garlic clove) and slice thickly. Place in a bowl with the veggies.
Place pork in a bowl. Add 1/2 tsp salt and 1/2 tsp chicken powder. Add one egg and whisk together.
Place a pan on High heat and add some vegetable oil. Add the garlic and ginger. Then in another bowl, mix 3 large spoonfuls of corn starch with 6-9 spoonfuls of water.
In a separate wok, heat some vegetable oil on high heat - about 1 inch deep.
Add some ketchup to the garlic and ginger and let ketchup sizzle for 2-3 minutes, stirring.
Below is a picture of how much ketchup to add. Mr. Yan was driving me crazy with his lack of exact measurements!
Add 1/2 cup water and about 1 tsp of soy sauce. Add 1 tbsp tomato paste. Add 3 big spoonfuls of sugar. Add the water and cornstarch mix slowly, stirring after every spoonful. The sauce should thicken and look like this:
Add the rest of the corn starch (1 cup, minus the 3 spoonfuls already used in the sauce) to the pork and coat the pork.
Place 1/3 of the pork in the hot oil, making sure that the oil is deep enough to cover the pork. Let fry for about 1 minute, then remove with a slotted spoon and put on a plate. Do this with the other 2/3 of the pork.
Place 1/3 of the pork in the hot oil, making sure that the oil is deep enough to cover the pork. Let fry for about 1 minute, then remove with a slotted spoon and put on a plate. Do this with the other 2/3 of the pork.
While the last third of the pork is still in the wok, drop the rest of the pork back into the wok and swish all the pork around for 2 minutes, letting the outsides brown a bit. Then add the veggies and swish around for another minute, then remove from heat.
Remove the veggies and pork from the oil with a slotted spoon and place on a separate bowl or plate.
Clean and dry the wok and return to high heat.
Place the sauce in the wok (will sizzle) and add 2 spoonfuls of the used oil. Add the pork and vegetables. Toss, then remove from heat and serve.
