Mix well, and add enough hot water for the dough to hold together, but not too much. At the most a cup, though do so gradually, because if the dough is too moist you'll have to add more flour, and that will toughen the dough. Work everything into a ball and knead energetically for 5-8 minutes, or until the dough is smooth and elastic. Because of the lard in the dough, there should be no problems with the dough's sticking to your work surface.
Cover the dough ball with a cloth and let it rest for a half hour.
