Homemade Crackers

From http://www.recipetips.com/recipe-cards/t--1973/homemade-crackers.asp

1 1/4 cups flour (divided) - white, whole wheat, rye, or any finely ground grain such as cornmeal or buckwheat
1/2 teaspoon salt
2 tablespoons butter, canola oil or olive oil; more as needed
4 tablespoons water; add more as needed
1 teaspoon seasoning such as chili powder, dried herbs etc (optional)

1. Preheat oven to 400° F.
2. Mix together well, preferably in a food processor, 1 cup of the flour, 1/2 teaspoon salt and oil or butter ( use smaller amount for crisper crackers, or a larger amount for a richer flavor). Add 3 tablespoons water and mix well. Gradually add more water, mixing after each addition, until mixture forms a compact ball. If it seems too sticky to handle, add more flour.
3. Sprinkle a work surface (or a baking sheet-sized piece of parchment paper) with some of the remaining flour then press and roll the dough to about 1/8th inch thick. Try to get it fairly uniform. If the dough is too dry to roll out, return it to the food processor and add a little more water. If necessary to prevent sticking, dust your hands and the rolling pin with a little more flour.
4. Put the rolled-out dough on a baking sheet dusted with a little flour (if you've used parchment paper, transfer dough and paper to baking sheet) and bake 10 - 15 minutes, until somewhat brown.
5. Cool and break into pieces. If making several batches, mix another while the first one bakes. You can re-use the parchment paper several times.
