Start by rolling up your de-boned lamb, if this has not already been done for you.
Cut slits into the meat and insert your garlic pods, I cut mine into half or thirds and evenly distributive throughout your meat. You can also shove in some rosemary sprigs.
In the center of the lamb insert 2 to 3 crushed garlic cloves and a few more sprigs of rosemary
Rub olive oil all over your meat and season with Salt, fresh black pepper and red chilli flakes and thyme.
Switch your IP onto Saute mode, throw in a knob of butter and a glug of olive oil. Brown your lamb evenly on both sides.
Remove lamb from the pot and deglaze with about 3/4 cup of water
Return back to the pot, put the lid on and switch to Pressure Cook, "high". Depending on the size of the meat select your cook time. For a 1kg I would recommend 50 minutes to 1 hour. For a 2kg I would probably suggest about 1 hour 15 minutes. Once cook time has completed allow pressure to release naturally. (approx 20 minutes).
Remove your lamb and allow to rest before carving (If you prefer a browner meat you can grill it for 5 minutes in the oven.
Whilst the meat is resting, create a cornflour slurry with about 2 teaspoons of cornflour and a little cold water to mix. Hit saute mode again and add the slurry to the remaining liquid and stir to mix up the most delicious gravy.
Serve with traditional crispy roast potatoes, sweet orange glazed baby carrots, green beans and spinach. Have some mint sauce on the side for a spectacular traditional English roast lamb !
