Mix the flour, water and salt together, and make sure the mixture is fairly dry.
Then roll it out to about 1/2 inch thickness, and shape it into a rectangle. Cut it into 3×3 inch squares, and poke holes in both sides.
Place on an un-greased cookie or baking sheet, and cook for 30 minutes per side at 375? (or 350? if you have a convection oven).
When it’s done, you’ll want to let it dry and harden for a few days, just out in the open. When it has the consistency of a brick, it’s fully cured. Then simply store it in an airtight container or bucket. To prepare for eating, soak it in water or milk for about 15 minutes, and then fry in a buttered skillet. You can eat it with cheese, soup or just plain with a little salt added. Any way you do it, it’s delicious!
