AP stands for all-purpose flour, which you can find in multiple brands in your grocery store. Ours is a blend of hard red and soft white wheats. This combination gives a lighter and tender crust and crumb (from the soft wheat), and enough structure to rise properly (from the hard red wheat). Our standard AP flour is a combination of Butler's Gold '00' and Mediterranean '00'. Our Premium AP is made from Rouge de Bordeaux '00' and Sonora '00'. You can use either of our AP flours for items such as quickbreads, waffles, biscuits, pies, cookies, and pan loaves. See these charts here and here for a full list of ideal flours for various applications.
