1. Preheat the Oven:

• Preheat your oven to 425°F (220°C). Line a baking tray with parchment paper to prevent sticking.

2. Prepare the Dough:

• In a large mixing bowl, combine the cooled mashed potatoes, whole spelt or barley flour, egg, and salt.
• Mix thoroughly until the dough comes together into a slightly sticky consistency.

3. Divide and Shape the Dough:

• Divide the dough into four equal portions.
• Dust your fingers lightly with flour to prevent sticking, then flatten each portion into a round disk, approximately 1/4-inch (0.5 cm) thick, directly on the prepared baking tray.

4. Prick the Dough:

• Use a fork to prick the surface of each flatbread. This helps to prevent bubbling during baking and creates the signature texture.

5. Bake the Flatbread:

• Place the baking tray in the preheated oven and bake for 15 minutes, or until the edges are golden and slightly crisp.

6. Serve:

• Serve the flatbreads warm, topped with butter, smoked or cured salmon, and fresh dill.
