Pour a scant tablespoon of the olive oil into a 9"-square cake pan; spread evenly to cover bottom and sides. Place all-purpose flour, semolina flour, 2 tablespoons of the olive oil, 1/4 teaspoon of the salt and all of the yeast in the bowl of a mixer fitted with a dough hook. (
The mixing can be done by hand as well.) Blend ingredients on medium speed. Reduce speed to low and = slowly add hot milk. Raise the speed to medium and continue mixing for 5 minutes (knead about 8 to 10 minutes by hand). Sprinkle bottom of cake pan with a little flour.
Remove dough from bowl and spread out evenly in pan. Cover with a towel and let rest for 30 minutes. Preheat oven to 400 degrees. Remove towel. Brush dough with 1 to 2 tablespoons of the olive oil. Sprinkle top with additional salt and rosemary. Bake for 20 minutes. Remove from oven and drizzle with remaining oil.
