I started baking my own Sourdough Bread several years ago. Began by mixing it by hand and then Patti had me get a KitchenAid, Professional 6000HD. Costco had a great price plus we used our rebate and did not have to pay much.
Now I do my bread and once a month make the bread for our Churches LORD'S Supper.....
Yep, this tastes better than store bought.
I am annal regarding flour so I use either King Arthur or Wheat Montana. Couple of times have used the CostCo Organic flour and it turned out well.....
