Preheat oven to 350 degrees F, and line a baking tray with some parchment paper.
In a deep bowl, first mix the dry parts and spices. When you mix everything together add the water and olive oil and continue mixing, now you can continue by hand. It is necessary to get a thick mixture that does not stick to the hands, which you can pull out into a crust with a rolling pin.
So you can play with the ingredients, if the mixture is too thick add a little more sparkling water, if it is a bit liquid add a little flour.
When you make a thin crust, using a mold take out the desired shapes. From this quantity I got 100 crackers the size of the pictures above.
Bake for 18-20 minutes. Leave them to cool down for about 10 minutes and they are ready to serve.
