Vindaloo is a dish that comes from Goa. My friend Allan is a Goan and he told me the origin of the word 'Vindaloo' comes from a mix of the Portuguese words for wine (vinho) and garlic (alho) - hence vindaloo. So there's no 'aloo' or potato in this recipe anywhere. But plenty of vinegar and garlic. Use a fatty part of the pork for the best results. Port fat rules in this recipe!
