Preheat the oven to 400 degrees F.

Combine dry ingredients: In a bowl, stir together the flour, sugar, baking powder, baking soda, salt, pepper, rosemary and garlic. 

In a small bowl, combine the water and vinegar. While stirring, add the water mixture to the flour mixture. Stir the mixture until a dough forms.

Turn the dough out onto a floured surface. Knead the dough for 2-3 minutes to make sure all the ingredients are incorporated.

Shape the dough into a flat, round disk no more than 1 1/2 inches high. Place the dough on a baking sheet, pizza stone or into a large cast-iron skillet. Dip a sharp knife into flour then cut a fairly deep "X" on top of the loaf.

Place the pan in the oven and bake at 400 degrees F for 30-40 minutes or until golden brown and the crust is firm. Halfway through baking time, brush the top of the loaf with milk for a softer crust.

When the bread is done, remove it from the oven and while still hot brush it with the melted butter. The butter will add flavor as well as soften the crust.
