A delicious and authentic chicken recipe for Ginger Beef Stir Fry, prepared with traditional seasonings and techniques.
Halve the flank steak lengthwise into two big pieces, then slice against the grain into 1/4” (4-cm) thick pieces.
Beat the egg in a medium-sized bowl. Add the sliced beef, ginger, bicarbonate of soda and salt. Mix well and let marinate for 20 minutes while preparing the other ingredients.
Combine the sauce ingredients in a medium bowl and mix well.
When you’re ready to cook, add the 1/3 cup cornflour to the marinated beef, 1 tablespoon at a time. Stir to coat the beef, until it forms an uneven coating with a little dry cornflour left unattached.
Heat 2 tablespoons of oil in a wok (or 24” frying pan) over medium-high heat until it shimmers. Cook in batches, add the beef and spread it into a single layer in the frying pan. Cook without touching the beef for 3 minutes, or until the bottom has browned. Flip to brown the other side, 2 minutes or so. Transfer the beef to a big plate and repeat with the rest of the beef. Once all the beef is cooked, remove the pan from the stove. Let cool for 2 to 3 minutes. (*Footnote 2)
Place the pan back onto the stove and turn to medium heat. Add 1 tablespoon of oil.
Add the spring onions, ginger, and garlic. Stir a few times to release the fragrance.
Add the sweet peppers and baby bok choy. Turn to medium high heat. Stir and cook for 1 minute.
Stir the sauce again to dissolve the cornflour completely. Pour into the pan. Stir and cook until it thickens (*Footnote 3). Add back the beef pieces. Stir to coat the beef with sauce.
Transfer everything to a plate immediately and garnish with roasted sesame seeds. Serve hot over steamed rice as a main dish.
