Put the oven on 300F

Stir until you have an even dough that does not crumble up. Add a bit more water if it crumbles.

Put non sticky parchment paper on 2-3 baking sheets. I use 3, one is 11 x 17 inches and two are slighter smaller.

Divide the dough on the sheets and tear an extra paper and put on top of the dough.

Use a rolling pin to spread the dough to an even very very thin layer. The thinner the better they will taste.

Take off the paper on the top and use the same paper for the other sheets.

Finally you sprinkle some salt flakes over the dough and use a knife to cut squares.

Bake in the middle of the oven for 1.10 - 1.15 min

Good luck
