I have tried many methods of starters. The pineapple juice and water and flour. With no success. Most end up smelling like puke. So I ended up buying some starter dust off ebay. The starter doesnt smell sour yet after a week. I am using king arthur unbleached and 2 cups warm water and 2 cups flour. I see mild activity and it doubles in size and then shrinks. it just smells like flour and water. Please help!
