Place both types of flour in a large mixing bowl and stir to mix well. Make a well in the center of the flour mixture and add water a little at a time, stirring with your hands until a dough is formed. You may need more or less water, depending on the humidity in your kitchen.

Place the dough on a floured work surface and knead it like bread for 8 to 10 minutes until smooth and elastic. Cover and let stand for 10 minutes at room temperature.
