Cook The Pork
Cut the pork shoulder into large cubes (about 5x5cm). Place it into a bowl with the garlic, bay leaf, oregano, cinnamon and cloves. Cut the orange into quarters and squeeze over the juice. Throw the orange quarters in too. Season and toss everything together then transfer to a medium saucepan, small enough so that the pork fits tightly together.
Use a microwave to melt the lard and pour it over the pork until it’s just covered, then place a lid on the pan. Cook in the oven for 3 hours, until the meat is very tender and falls apart easily.
