Knead all the ingredients to a smooth consistent dough, rest for 30 minutes.
Divide the ball into 8 even pieces and roll each into a ball and rest for 15 minutes. When the dough is resting it should be covered with a damp cloth.
Roll each ball out very thin, a mixture of 50:50 flour to coarse polenta is good for this, avoid using too much as you dont want to dry the dough, work quickly and keep all dough covered.
Cook quickly on both sides on a very hot chargrill and wrap in a clean tea towel. Once cooked, use immediately.
