There you are Chouxbacca. Hope you’ll enjoy it. A few comments, I never grease the pan, there is no need for it. The focaccia cooks in about 12-15 minutes at 450°F when you make it without the pesto.
Focaccia
1 tablespoon active dry yeast (1 package)
4 1/2 cups unbleached all-purpose flour (exact measure)
1 ¼ teaspoon salt
1 cup hot water
1 cup hot milk (120°F)
¼ cup olive oil
In a large bowl with a whisk or in the work bowl of a heavy duty electric mixer fitted with the paddle attachment, combine the yeast, 2 cups of the flour and the salt. Add the hot water, hot milk and the olive oil. Beat until well combined, about 2 minutes, Add the remaining flour 1/2 cup at a time, until a soft dough that just clears the sides of the bol is formed. Switch to a wooden spoon when necessary if making by hand. The dough will be sticky, soft and oily. Scrape down the sides of the bowl, drizzle the sides with a bit more olive oil and cover loosely with plastic wrap. Let rise at room temperature until doubled in bulk, about 1 hour.
Oil or parchment-line a 17x11 inch baking sheet. Turn the dough out onto the baking sheet. Spread and gently pull the dough flattening it to fit the entire baking sheet. Let rest uncovered at room temperature for 15 minutes.
Twenty minutes before baking, preheat the oven to 450 8F, with a baking stone on the bottom rack if desired. Place the sheets or pans directly on the hot stone, if using, or on the lowest oven rack and bake 15 minutes. Reduce the oven thermostat to 350°F and continue to bake until golden and the bread springs back when pressed gently, 20 minutes more. Let coolin the pan 5 minutes. Using a spatula, loosen the sides with a knife and slip the bread out carefully onto a clean dish towel or to a cooling rack. Cool and serve at room temperature.
