250g pork tenderloin
20G starch
1 egg
2 tablespoons salt
5g sugar
30g ketchup
Proper amount of water
Appropriate amount of onion and ginger
Appropriate amount of edible oil
A little white vinegar


Step 1
Wash the pork tenderloin and cut it into long strips about 4cm long and 1cm thick.

Step 2
Put the chopped tenderloin into a bowl, add salt, onion and ginger, stir well, and marinate for 15 minutes.

Step 3
Put starch in another bowl, and then pour egg white and an appropriate amount of water. (starch and flour come from different sources. Flour is the powder directly ground from wheat or other grains after peeling, while starch is a polysaccharide obtained from the separation of protein and other substances from flour. It is mainly used in food, glucose, maltose, etc.)

Step 4
Stir evenly until it becomes powder. (when the chopsticks are picked up, the slurry will drip down evenly)

Step 5
Put the cured tenderloin into a bowl, stir well and size it.

Step 6
Put an appropriate amount of oil into the pot and cook until 60% hot. (measuring oil temperature with chopsticks: [cold oil temperature] 1-20% hot. When chopsticks are put into oil, there is no reaction. At this time, they are suitable for frying nut foods, such as fried peanuts, and also suitable for frying sauces. Low oil temperature] 3-40% hot. When chopsticks are placed in oil, small bubbles will appear around them. They are generally used for smooth frying, smooth frying, oil explosion and other dishes. [medium oil temperature] 5-60% heat. If you look closely at the oil surface, there will be ripples, and the bubbles around the chopsticks become dense, but there is no sound, which is suitable for frying pan and frying vegetables. High oil temperature] 7-80% heat. There are a lot of bubbles around the chopsticks, and there is a crackling sound, which is suitable for frying or frying meat and fish.)

Step 7
Turn to medium low heat and put in the tenderloin strips one by one. About 1 minute, deep fry until the tenderloin turns golden.

Step 8
Drain the fried meat strips and put them in a bowl for standby.

Step 9
Add a little oil into the pot and transfer in an appropriate amount of ketchup.

Step 10
Turn on a low heat until the ketchup boils, add an appropriate amount of water, sugar and salt, stir evenly, and boil into a viscous soup.

Step 11
Put the fried tenderloin into the pot and stir fry, so that the meat strips are evenly wrapped with soup.
