2 c. unbleached white flour
1 c. water (with 1-2 tsp salt added to the water)
1. Mix the flour with the salted water until the flour just comes together. You might not even need the entire cup of water.
2. Knead it into a random shape and roll it out to 1/2" thick on parchment paper.
3. Cut into squares, rectangles, dodecahedrons or whatever shape you prefer your crackers to be in. You could probably use cookie cutters too.
4. Use fork tines to prick holes (but don't pierce the dough) across all the crackers. This is to keep the dough from rising.
5. Transfer the parchment paper (with the crackers on top) to a baking sheet.
6. Bake for 40 minutes or until the tops/edges are golden brown. Let cool in oven. The drier the cracker, the more cracker-like it will be.
In retrospect, using a pasta machine or rolling the crackers out to a much thinner thickness would be better. Once these crackers really dry out, they are brick-like hard. This is probably why matzo crackers are rolled out to a 1/8" to 1/4" thickness.
