In a mixing bowl, whisk together flour and salt.
Cut cold butter or shortening into small cubes.
With a pastry cutter (or fork), cut butter/shortening in the flour until the dough pieces are coarse crumbs, about the size of peas
Sprinkle 1 Tbsp water over the crumble and gently toss, with fork.
Repeat by tablespoons until the water is gone.
Check your dough to see if it is ready or if it needs more water ( should be tacky and hold together)
If it is crumbly and falling apart add a few drops more water. Do not over mix. ( You don't want the bits of butter to melt.)
form it into a ball and cover with plastic wrap and refrigerate.
Chill for 4 hours or overnight.
