Mix all dry ingredients, when stir in sesame oil. Gradually add water, adjusting as needed. Dough is ready when it can be formed into a ball (but don't make it too wet, as rolling out will be really hard).
You can dust a surface and roll out with a pin, or press with a tortilla press (which is what I do). I like to press numerous small circles, so they cook more evenly. The edges will brown before the center gets done.
Put dough on a non-stick cookie sheet and prick with a fork. You can cut them apart with a pizza cutter now, or lightly score them--however you like. I leave them in my little circles. Bake 15-20 minutes or until crisp in the center!
Servings will depend on how big you make your crackers!
