Preheat oven to 350F/180C.
Add sourdough discard, flour, butter, maple syrup, pistachios, cranberries, spices (and salt if adding) to a mixing bowl and bring the ingredients together to form a shaggy dough.
Knead the dough in the bowl until it forms a smooth pliable dough (it is a soft dough and will be slightly sticky, but still very easy to handle). If it's too sticky, add a little more flour. The stickiness will depend on your discard.
Place the ball of dough onto a piece of parchment paper and push into a rough rectangle. You can divide the dough into two balls if you'd prefer and roll out two sheets.
Place another piece of parchment paper on top of the dough.
Now roll out to a thin sheet of dough using a rolling pin. You want it around 1/16" or 1.5mm thick. The thinner you can get it the better.The parchment paper on top will stop the dough sticking to the rolling pin. Place parchment paper with dough on top onto a baking sheet.
Brush dough with olive oil and sprinkle with salt or cinnamon sugar.
Bake at 350F/180C for around 25 minutes or until lavosh is golden and crisp.
Let the piece of lavosh cool on a wire rack before breaking into pieces.
