In a small bowl, whisk flour your flour together with your beef stock and pour this mixture into the pressure cooker also.
Finally, add the remaining ingredients and seal your cooker.
Microwave your cooker on high power 30 minutes. Then, remove it from your microwave and allow it to release its built up naturally. Be sure to wait until red pressure indicator fully lowers, about 10 minutes, before opening.
