Combine all the ingredients in a bowl and knead into a soft dough using hot water.
Divide the dough into 6 equal portions.
Roll out each portion between two sheets of plastic into a thin circle of 175 mm. (7″) diameter. Dust the tortillas generously with flour to make the rolling easier.
Lightly cook the tortillas on a non-stick pan.
Cut each tortilla into 6 triangular pieces.
Place the tortilla pieces in a single layer on a non-stick baking tray.
Bake at 190°c (380°f) for 7 to 8 minutes or until the tortilla chips are crisp and lightly browned.
