Preheat your oven to 375°F or 190°C.
Mash or blend the dates into a thick paste.
Combine the date paste with crushed walnuts, barley flour, salt, and olive oil in a bowl until a dense dough forms.
Shape the mixture into small round discs and gently press your thumb into the center of each one.
Place them on a parchment-lined baking tray and bake for 25 to 30 minutes until they are just golden at the edges.
Let them cool slightly before drizzling with honey and sprinkling with sesame seeds.
If using saffron, crush a small pinch and sprinkle over the top just before serving.
