Take Note;- We are about to add water, Adding the water to short crust pastry is a critical part of the recipe, not enough and your pastry won’t hold together for rolling, add too much water and the pastry will be easy to work with, but produce a harder, chewy and less attractive pastry. A key point here is you can always add a little more water at any time, but you can’t remove water if you add too much.
We are not going to mix our pastry to a smooth dough at this point, even after we have added the water the pastry will still look like a crumbly slightly moist mix, not at all suitable for rolling out.
