Toss the beef joint in salt and pepper. Rub sage into the into the beef too.
Heat the oil in your Instant Pot on the saute setting and brown all sides of the beef.
Click the cancel button and leave to rest for 5 minutes.
Remove the beef from the Instant Pot and place it on a plate or a chopping board or whatever is easiest.
Peel and chop the carrots into big chunks, peel the fresh garlic and quarter the potatoes with the skin still on them.
Place the vegetables and the garlic in the bottom of the Instant Pot and using your hands mix it into the juices that are left over in the bottom from sautéing the beef.
Position the beef on top of the vegetables.
Add 250ml of vegetable or beef stock (I used that new powdered veggie stock mix for this and it was fantastic).
Cook on low for 8 hours.
Serve with Paleo style gravy.
