It's not crispy but I do a really nice beef in a spicy szechuan sauce.
750 grams of beef rump steak
2 cloves of crushed garlic
2 teaspoons of fresh grated ginger
2 tablespoons dry sherry
1 tablespoon soy sauce
3 tablespoons black bean sauce (if you have a Chinese grocery shop, buy it from them. Black bean sauce tastes completely different from a normal supermarket)
2 onions cut into wedges
1 red capsicum cut into strips
300 grams of broccoli cut in florets.
250 grams of snow peas (you can substitute for sugar peas or any young fresh peas)
chilli flakes
1 tablespoon cornflour
1 egg
1/2 teaspoon bicarb soda
peanut oil or any vegetable oil
1/4 teaspoon sesame oil
It's better to do the preparation well in advance. Once you start cooking, it takes very little time.
Cut the beef into thin slices. If you put the meat in the freezer for 30/40 minutes it'll be easier to cut.
In a bowl, beat the egg, add the soy sauce, 1/4 teaspoon of sesame oil and the bicarb soda. Beat until all combined and add the beef making sure it's well coated. Put the bowl in the fridge for 2-3 hours.
About 30 minutes you want to serve dinner, put the cornflour in a mug with a bit of cold water. Mix well and add the soy sauce and black bean sauce. Fill the mug with cold water until 3/4 full.
In a wok, put some peanut oil and when it's hot add the onion, capsicum, broccoli and snow peas and cook for 3/4 minutes constantly stirring. Set aside the vegetables in a bowl.
Add another splash of oil to the wok and on high heat add the fresh ginger, crushed garlic and chilli flakes. The ginger and garlic will brown very quickly so after a few seconds add the beef and cook on high heat until its browned but not fully cooked. You need to still see pink in the meat before you add the vegetables. Toss the meat with the vegetables for a few seconds, add the sherry and toss some more. Add then the cornflour sauce and keep cooking on high heat until the sauce has thickened. Serve immediately.
It sounds complicated but it's one easiest meals to prepare if the preparation has been done before the cooking begins.
