Flaky & delicious - just like your mama used to make it!
In a medium bowl, combine the flour and the salt. Add grated butter, and toss together with the flour to incorporate.
Sprinkle the water, 1 tablespoon at time, tossing with a fork until all flour is moistened. Additional water can be added 1 tablespoon at a time if needed, but don't make the dough too wet.
Gather dough into a ball, and shape into a flattened round. Leave the dough in the bowl, covered with a towel, until ready to use.
If you're making the dough ahead of time, you can wrap it in plastic and store it in the refrigerator. Bring the dough back to room temp before rolling.
