Note Pasilla, chipotle, guajillo and ancho chillies are available from Monterey Mexican Foods. A good homemade stock or butcher's stock with a high gelatine content is essential to the success of this dish. The batter will thicken the longer it is left, so you may need to add a little water to thin it out as you work. White masa harina (also known as masa flour or harina de maíz) is a white nixtamalised corn flour; it's available from Monterey Mexican Foods and Fireworks Foods.
