Part 4/6:
Mix the beef in batches with the ice water, ensuring it feels sticky after each addition. This hydration process continues until the beef has a shiny surface, indicating it is well-marinated.
Afterward, incorporate the egg white and corn starch, taking care not to overmix—just enough to coat the beef evenly. Cover the bowl with plastic wrap and let the beef rest for 30 minutes.
Checking the Marination
After 30 minutes, check if there is excess liquid at the bottom of the bowl. If not, congratulations—you’ve successfully marinated your beef!
Divide the beef into portions. If you want a quick stir fry, set one portion aside. The rest can be vacuum sealed and stored in the fridge for three days or frozen for up to two weeks. Remember to label the bags with the date!
