In a large mixing bowl, combine flour, salt, and baking powder. Cut in the shortening until the mixture resembles coarse cornmeal.

Add the water and mix until the dough can be gathered together. If necessary, add water (1 teaspoon at a time) until the dough forms. Cover with a damp cloth and let it rest for 15 minutes.

Divide the dough into 12 equal pieces and roll into rounds. Using a lightly floured surface and rolling pin, flatten each into a circle about 7 inches across.
