Start with two cups of flour in a bowl, to which you add the salt.
Next, slowly add the water.
Mix well. Your goal is to make it into a consistent dough that you can roll out and cut. If it gets too watery, add more flour.
On a floured table, roll out your dough with a floured rolling pin until it is about ¼ inch thick.
Cut it into whatever shapes and sizes you like - typically 3x3 inch (7x7 centimeter) squares. It's important that all the pieces be roughly the same size so they cook at the same rate.
Preheat the oven to 375 °F (190 °C).
Place the biscuits on an ungreased baking sheet, and make sure they are evenly spaced.
Next, dock the biscuits. This means poking holes in the dough so it will dry properly and will not rise. Folks usually cut 16 holes in a 3 inch by 3 inch square, but I poked more holes so they cook faster. Use your fork to keep them evenly spaced and sized.
Cook them for 20 to 30 minutes at 375 °F (190 °C).
Flip them over with a spatula, then cook them for another 20 to 30 minutes.
Remove the biscuits from the baking sheet, and place them on a cooling rack until they reach room temperature. Store in an airtight container.
