Crispy Orange Beef

Another tasty and quick recipe for dinner; this is on the sweet side, but not overly so.  When I make it again (which I absolutely will!), I plan to try adding just a little bit of red pepper flake to see if I can achieve an even better result (will post results when I do, of course).
Here is the original recipe, which I followed fairly closely:

Ingredients:

1 lb. flank steak, cut in small strips across grain
1/3 c. white sugar
1/3 c. rice vinegar
2 T. frozen orange juice concentrate
1 tsp. salt
1 T. soy sauce
1/4 c. cornstarch
2 tsp. orange zest (this was the zest of 1 orange for me)
2 T. fresh grated ginger
1 1/2 T. bottled minced garlic

2 c. oil for frying (I used canola)

Instructions:


1. Line a baking sheet with paper towels.  Spread meat out on paper towels and dry in fridge for 30 minutes.

2. In a small bowl, combine the sugar, rice vinegar, orange juice concentrate, salt, and soy sauce.

3. Coat dried beef in the cornstarch (I just tossed them together on the paper towel).

4. Heat oil in a wok over medium-high heat.  Fry the beef in small batches until crispy and slightly browned and set aside.

5. Drain all the oil out except 1 T.  Add the orange zest, ginger, and garlic; cook briefly until fragrant (around 1 minute).

6. Add the soy sauce mixture and bring to a boil.  Stir and boil for around 4-5 minutes, or until syrupy and thickened.

7. Add beef, stir to coat and heat thoroughly.

8. Enjoy (I paired it with boiled Basmati rice--perfect!)
