1/3 cup + 1/3 cup + more for drizzling: Empeltre EVOO, or similar, intense olio nuovo with excellent chemistry: super low FFA, >.2, super high oleic 79+, and super high phenol count of 400+, with strong savory flavor notes and heady bouquet.

1 package active dried yeast, or 2 1/4 teaspoons
1 tablespoon fresh rosemary leaves rough chopped

If making the dough in your bread machine, follow its instructions for the order of adding ingredients. In the bowl of a stand mixer combine the water sugar and yeast. Allow the yeast to bloom for about 5 minutes, Add 1/3 cup of olive oil, mashed potatoes and sea salt. Mix to combine.
With the mixer running on the lowest speed, begin to add the flour, cup by cup, until the dough has come together and becomes elastic and just slightly tacky. Reserve any leftover flour for rolling the dough out.
Cover the bowl and allow the dough to rise in a warm place for one hour.
On a rimmed baking sheet lined with parchment, gently push the dough to the edges, using fingertips to stretch it and make dimpled indentations. Cover and allow the dough to rise for another hour in a warm place.
Preheat the oven to 375 degrees.
Distribute the thinly slices shallots and rosemary evenly over the focaccia. Drizzle with remaining 1/3 cup of extra virgin olive oil, a sprinkle of fresh ground pepper, and a sprinkle of sea salt. Bake for approximately 35-40 minutes until golden brown. While still hot out of the oven, drizzle with more extra virgin olive oil to taste. Serve warm.
