Instructions
Pre-heat the oven at 190 C° / 380 F°
In a bowl mix well the rice and sorghum flour, the starch, baking powder and salt
Add the water and 1 tablespoon of olive oil to the dry ingredients and whisk thourougly until you have a smooth uniform dough
With a mandoline slice thinly the potato and the onion
Generously grease the baking pan with a 2 tablespoons of olive oil and add the focaccia dough onto the pan, spreading it evenly (the olive oil will probably cover the borders, it's totally fine, it will make the focaccia more crunchy)
Top the batter with the sliced onion and potato, add finely chopped fresh rosemary, a generous drizzle of olive oil and a sprinkle of salt
Bake for 25-30 minutes, or until it is golden brown
I love to add extra onions on top, after slicing them and sauteing them in a pan with a little oil, salt and pepper
For extra flavor you can add crumbled feta or vegan ricotta on top, right after the focaccia is out of the oven.
