⅓cupraisins soaked in water for ten minutes or dried goji berries roughly chopped* (see note)
⅓cupchopped walnuts or pistachios
Preheat the oven to 175ºC / 350ºF and line a baking sheet with parchment paper.
Put all the ingredients in a medium bowl and mix with your hands until a dough is formed. Shape the dough into a ball, put it back into the bowl, cover with a clean kitchen towel and let it chill for approximately 30 minutes in the fridge.
Place the chilled dough on a sheet of parchment paper with another sheet on top, and roll it out evenly with a rolling pin to approximately ½ inch thick. Cut into squares with a pizza cutter, or use a cookie cutter. The dough is a little fragile so you’ll have to be gentle with it. You might need to use a metal spatula to transfer the cookies onto the baking sheet.
Bake in the center rack for 5 minutes, then rotate the baking sheet and cook for 5 more minutes.
Let it cool completely before you gently transfer them into a container.
* I didn't chop the raisins but you should definitely do that, like my friend did. It's much easier to cut the dough into cookies this way. In that case you don't need to soak the raisins in water.
