In a bowl, add the flour, salt, garlic and the dried thyme and stir well.
Grate the cheese and add to the previous mixture. Stir again.
Add the water, little by little, while stirring, until a consistent (but not too dry) dough is formed.
Form a ball with the dough and refrigerate for 10 minutes.
Remove from the refrigerator and place the dough on a baking paper. Flatten slightly and place another baking paper on top.
Roll out the dough with a rolling pin until it is about 0.5 cm thick.
Cut into cracker shapes with a cookie cutter or a sharp knife.
Sprinkle with the sesame seeds.
Bake in a preheated oven at 160º/170º for 12 minutes or until golden brown.
Let them cool to crisp and serve.
Notes
If you want extra crispy crackers, you can turn off the oven and leave it slightly open while the crackers are still there. Don't leave it more than 10/15min, so they don't burn.
You can use another cheese, as long as it is easy to grate.
As for the spices, use whatever you want: dried rosemary, smoked paprika, cumin powder, sundried tomatoes, you name it.
These crackers can be made with other flours like wheat, whole wheat, or spelt. If you use finer flours like almond, rice, or coconut flours, you have to be aware of the quantities.
You can serve it with a dip or with a cheese and ham platter.
