4. Add mustard powder, tomato paste and garlic and cook for 1-2 minutes more.
5. Add stout beer and thyme to the pot and deglaze by using a wooden spoon to scrape the brown bits from the bottom of the pot.
6. Nestle the beef into the vegetable mixture.
7. Turn the pot off by selecting CANCEL, then secure the lid, making sure the vent is closed.
