Preheat oven to fan-assisted 130C / 150C / 300F / gas 2.
Mix the ginger beer, garlic puree, onion, vinegar, tomato puree and thyme in a casserole pot.
Mix together the ingredients for the pork mix and rub all over the pork.
Add the pork into the ginger beer sauce, cover and cook in the preheated oven for about 3.5 hrs or until the pork falls apart when shredded.
Remove the pork from the liquid (don’t discard this), cover with foil and let stand for 15 mins before shredding.
Heat the remaining liquid on a cooker and cook until the liquid has reduced in half.
Mix in a thickened ginger beer sauce with the shredded pork to your taste and serve with lots of buns and coleslaw etc for people to serve themselves
