Place the water in the bowl of a stand mixer.

Add the sugar, sprinkle the yeast over the water and let it bloom until bubbly, 5 to 15 minutes.
-

In a mixing bowl, combine the all-purpose and wheat flours together with the salt and chopped rosemary.
-
4
Gradually add the flour mixture to the bloomed yeast in the mixing bowl.

Then add 1/2 cup of the olive oil.

Oil a 9-by-13-inch baking sheet with the remaining 1/2 cup olive oil.

The more dimples you make, the more texture the bread will have.
