Combine some of the flour (only enough to coat all the beef well), beef, salt and pepper in a plastic bag and shake. Remove the beef from the bag, leaving all excess flour in the bag.
Turn heat to high. Add beef (without excess flour from bag) and stir for 2 minutes to caramelise.
Stir through remaining ingredients. Bring to the boil to cook off the alcohol.
Close and lock Pressure Cooker and bring to pressure on medium/high heat using setting 2 (Pressure is reached when the red Pressure Indicator has risen)
Once at pressure, turn down the heat as low as possible whist maintaining at pressure, and cook for 30 minutes. (If cooked on excessive heat the beef may burn.)
Slow release pressure by removing from heat and allowing to cool down naturally. This will take approximately 10 minutes. Pressure has been released when the red pressure indicator has dropped.
Serve with mashed potato or rice.
Notes
The beef is cooked after 30 minutes but melt-in-the-mouth after 45 minutes.
