Instructions
- In a large bowl, combine the mashed potatoes, flour, yeast, salt and 1 tbsp of olive oil, and mix in enough water to form a soft dough (you may not need all the water).
- Knead lightly, cover with plastic wrap, and leave to rise for about 1 hour.
- Preheat the oven to 180C/350F/Gas Mark 4.
- Lightly oil a large baking tray.
- Place the dough in the middle, and work it out to the edges to form a square or rectangle.
- Top the dough with the uncooked potato slices and the rosemary, season with salt and pepper, and drizzle with the remaining oil.
- Bake for 50 minutes, covering if the focaccia is getting too brown.
