A healthy crispbread/cracker recipe from Sweden prepared with Rye flour, wheat flour with the hint of caraway seeds and sesame seeds.
From my experience, I would suggest you can try different flours for this recipe. You can mix rye, wheat, and APF or just go with rye flour only.
Oats and sugar are optional.
If you cannot source caraway seeds, then replace it with cumin seeds.
If using a pizza stone, carefully read the usage instructions and use it accordingly. Please be careful while handling the hot stone. Also, make sure you sprinkle semolina or corn meal. It helps the wafer not to stick on the stone.
Adjust the amount of sesame and caraway seeds as per your preference.
