Ingredients List
-
Main Ingredients:
400g pork tenderloin (preferably pork hind leg “plum meat”), 1 egg white -
Crispy Batter:
6 tbsp potato starch, 3 tbsp all-purpose flour, 5 tbsp water -
Sweet-Sour Sauce:
8 tbsp ketchup, 4 tbsp white sugar, 3 tbsp white vinegar, ½ bowl water -
Essential Seasonings:
1 tbsp minced ginger, 2 tbsp minced garlic, 2 tbsp cooking wine, ½ tbsp salt, ⅓ tbsp white pepper
Step-by-Step Instructions
-
Prep the Tenderloin: Lay the tenderloin flat on a cutting board. Cut against the grain into 0.8cm-thick slices, pat them loose, then dice into strips the thickness of a pinky finger.
-
Marinate the Meat: In a bowl, combine the meat strips with egg white, ½ tbsp salt, 2 tbsp cooking wine, and white pepper. Stir clockwise for 3 minutes until sticky, then refrigerate for 20 minutes.
-
Make the Batter: Mix starch and flour at a 2:1 ratio. Add ice water in three batches, whisking until the batter reaches a yogurt-like consistency that can form thin threads.
-
Heat the Oil: Pour oil into a pot (enough to submerge the meat). Heat over high heat until inserting a wooden chopstick causes fine bubbles, then reduce to medium heat.
-
Fry the Meat: Dip each strip into the batter and place them in the oil with space between. Fry until light yellow, then remove. When the oil bubbles vigorously around a chopstick, return the strips for 30 seconds until golden brown.
-
Drain Excess Oil: Transfer all strips to a colander. Off the heat, pour hot oil over them for 10 seconds to release extra grease.
-
Sauté the Sauce Base: In the remaining oil, fry ginger and garlic until fragrant. Switch to low heat, add ketchup, and stir until it releases red oil.
-
Develop Sweet-Sour Notes: Add sugar and cook until caramel-scented, then pour white vinegar along the pot edge to enhance the aroma.
-
Thicken the Sauce: Pour in water and bring to a boil. Stir in a slurry (2 tbsp cornstarch mixed with 4 tbsp water) until the sauce thickens evenly.
-
Final Touch: Toss the tenderloin in the sauce until fully coated. Turn off the heat when the aroma peaks and the sauce glistens!
