Instructions
- 1
Thinly slice beef on an angle into 1/4-inch thick pieces that are 2 inches in length. Transfer sliced beef into a large bowl. Tip: To thinly slice beef, freeze it for 45-60 minutes so the exterior becomes hardened and use a sharp knife to slice it.
- 2
Marinate beef strips with marinade ingredients as listed above for 10 minutes.
- 3
In a small bowl, combine sauce ingredients as listed above and set aside.
- 4
In a separate bowl or on a large plate, add cornstarch and evenly coat each slice of marinated beef in the starch ensuring no bald spots. Transfer the coated pieces to a large plate.
- 5
Heat vegetable oil in a large pan on medium heat and fry beef in small batches in a single layer for 1-2 minutes until crispy. Do not over fry. Remove cooked beef and transfer to a wire rack or paper towel lined plate to remove excess oil.
- 6
Leave 1 tsp or 5 ml of vegetable oil in the pan and remove the rest. Reduce to low heat, sauté ginger, garlic, red chili for 10 seconds.

Pour in sauce to reduce and thicken.
