1. Preheat oven to 425 degrees Fahrenheit. Line sheet pan with parchment paper (optional, for easier clean up). Set pan aside.

2. Put all ingredients into a mixing bowl and stir well to combine. Once a shaggy dough is formed, use your hands to knead 3-4 times, or until dough forms into a ball.

3. Sprinkle a clean counter top or large cutting board with flour, and roll out dough in a rectanlge the same size as your sheet pan. Transfer dough to the pan, and slice into desired shape/size crackers with a knife or pizza cutter. You can also leave it whole and break into rustic chunks after baking. Sprinkle unbaked crackers with flaky salt, if using.

4. Bake crackers for 20-30 minutes, depending on how thick you roll the dough. Crackers should be a pale golden brown when you remove them from the oven. Let crackers cool completely, then serve or store in an airtight container at room temperature for up to a week.
