0.3 liter of flour. I use rye and wheat but take what you prefer! Corn flour works well.
0.5 liter of seeds and nuts and dried fruit. I use whaterevr I have home, sunflower seeds, pumpkin seeds sesame, linseed, almonds, goji berries, apricots. I use more seeds than nuts, becasue the texture is smaller, and it keeps better together.
0,5 teaspoon of salt
0.3-4 liter water
Mix the dry ingredients and add water.
Put baking paper on a 40 x 40 cm (or something around this size, doesn´t matter to much)tray and then spread the dough out with a dough scraper. It should be pretty thin.
Put the tray in the owen for 25 minutes in 150 degrees. Take out after that t cut in a size you want and thereafter put it in again for 35-45 minutes depending on how crispy you want it.
My favourite right now is with gojjiberries, and some cinnamon on top!
(This is just a base of a good recipie, then you can change a little bit and add or change ingredients.)
