    12 oz flank steak
  • After brining, remove meat from the brine and pat dry with paper towels. (this step will help the velveting egg white mixture adhere to the meat better.)
  • Add meat to a bowl along with egg white and white pepper.
    ½ egg white, ⅛ tsp white pepper
  • Mix until thoroughly combined. Add potato starch or corn starch, if using, and mix until all the slices of meat are covered.
    1 tbsp potato starch
  • Mix in neutral oil.
    ½ tsp neutral oil
  • Store in the fridge until ready to use.

P.F. Chang's Dark Sauce

  • Add chicken broth powder and sugar to a small pot with water.
    ½ tsp chicken broth powder, ¼ cup granulated sugar, ¼ cup water
  • Bring to a light simmer and whisk until dry ingredients are dissolved.
  • Remove from heat, add remaining ingredients, and whisk until dissolved.
    ¼ cup soy sauce, 2 tbsp soy sauce, 1 tbsp mushroom soy sauce, 1 tbsp oyster sauce, 2 tbsp rice cooking wine
  • The sauce can be stored covered in the refrigerator for up to 1 month.


Note 1: I recommend Kum Kee chicken broth powder (red label).
Note 2: I recommend Lee Kum Kee or Kikkoman.
Note 3: I recommend Shaoxing cooking wine.
*P.F. Chang’s uses dehydrated, minced garlic. You should be able to find this in the spice aisle at your local grocery store. To reconstitute, cover the amount of garlic needed with water for 20-30 minutes. Then strain, pressing out the extra water. Once reconstituted, the garlic can be used immediately or kept in the fridge for up to 1 week. 
*P.F. Chang’s currently uses Lee Kum Kee low sodium soy sauce (green bottle), Lee Kum Kee mushroom sauce, and Lee Kum Kee Panda brand oyster sauce (green bottle). In the past, they used Kikkoman soy sauce. So, it’s really up to you. I also recommend trying to track down Lee Kum Kee's premium oyster sauce because I believe it is superior to the green bottle. 
*P.F. Chang’s brines their meat for 24 hours.
