Instructions

1. Combine 2 tbsp. whole grain flour with 2 tbsp. unsweetened pineapple juice in a large container. Blend well with a wooden or plastic spoon and place uncovered in a warm spot where the temperature can be maintained at about 75 degrees F. Don’t use metal utensils because some wild yeasts don’t like them.

2. Add 2 tbsp. whole grain flour and 2 tbsp. unsweetened pineapple juice to the starter to feed the yeast 24 hours later. Blend well and put it back in its warm spot.

3. Stir the starter 24 hours later. Repeat the feeding and return the yeast starter to its warm spot.

4. Stir the starter 24 hours later. Discard all but ¼ cup. Stir in ¼ cup bread flour and 2 tbsp. de-chlorinated water. Wild yeasts don’t like chlorine. You’ll be discarding some of your starter with each feeding from now on, which will keep the volume manageable. Put it back in its warm spot.

5. Stir and feed the starter yeast every 24 hours until the dough begins to smell a little sour, bubbles throughout, and begins “growing” in size. It should look a little like a frothy chocolate milkshake when it’s ready.

6. Cover the container loosely and refrigerate. Don’t use a tight lid, which won’t allow developing gases to be released. Continue feeding your yeast once weekly thereafter, and return it immediately to the refrigerator

7. Take the container of starter out of the refrigerator two days prior to using it for baking bread and keep it at room temperature. Feed it once each day. Use 2 cups of starter for every package of active dry yeast you would otherwise use. Refrigerate the remaining starter.
