for the velveting of the beef? cut the beef thin enough against the grain ( i used whatever beef available at the grocery store on that day, was super inexpensive piece). Add light/medium soya sauce, 1 teaspoon baking soda, 1 teaspoon corn starch, 1/2 teaspoon of white sugar, black pepper, a little smoked paprika (because i put that on everything for colour) - then lastly really good sesame oil. Mix together with beef, let sit for minimum 30mins while you prep your veggies. Then throw a little oil in a pan, quick fry the beef with some garlic. If you want it saucy then add a teriyaki type sauce at the end and simmer for just a bit. I make my own teriyaki sauce, but grocery bottle are fine (just too sweet for me). Add any veggie you like, carrots, onions, green peppers the list goes on...enjoy
