Add the flour and salt, kneading with your hands until dough forms a soft ball. It will be crumbly at first but keep at it, it's worth it. If you want your crackers spicy add the jalapenos and cayenne pepper at this step.
Place dough on a floured surface and roll out with a rolling pin to 1/4 inch thick. Cut dough into small squares and place on parchment lined cookie sheet.
Place crackers on an ungreased cookie sheet with an inch between each piece of dough and bake at 350 degrees for 18 to 20 minutes or until lightly golden brown.
Allow crackers to completely cool on the cookie sheet. Remove and serve or place in an airtight container. Keep in airtight container for up to a week.
