Note White glutinous rice is available from select supermarkets and Asian grocers. Ask your butcher to debone the quail for you. White masa flour (also known as masa harina or harina de maíz) is a white nixtamalised corn flour; it's available from Mexican food shops including Monterey Mexican Foods.
We've used white corn tortillas for this recipe, because they have a smoother texture and a subtler corn flavour than yellow corn tortillas. If you don't want to use quail, substitute 800gm pork mince.
