How do you make the Samosa outside wrap? The flour and water + salt.

A lot of this wrapping outside, its either the cold water

The water + yeast

The water + baking soda

The water + baking soda+baking powder? I forget this Taiwan package what was in it. The combination might be. 

But the samosa its just the water and the flour + salt. 

You doing that often, you know what they are.
