A nice spicy stir fry for dinner last night.
First, I cooked the beef and moved that to a plate while I worked on the veg. Onions, peppers and carrots in a wee touch of oil. Highest heat my stove can handle. Move fast. Have all your ingredients ready! When they are soft, add the garlic, ginger and hot pepper flakes. Almost immediately--to prevent scorching--add the liquid; soy sauce and water.
Add some brown sugar to sweeten the sauce and simmer for a minute.
Return the cooked strips of beef to the sauce and simmer for another minute or so. There is a light corn starch coating on the beef, which in turn helps to thicken the sauce. Serve hot, over rice.
