Feeding and Maintaining Your Sourdough Starter

• servings: 1 item

Ingredients

1/2 cup (113g) sourdough starter

scant 1 cup (113g) King Arthur Unbleached All-Purpose Flour

1/2 cup (113g) water lukewarm

Directions

To store your starter at room temperature: Stir the starter thoroughly. Spoon 1/2 cup (113g) starter into a bowl; either discard the remaining starter or use it in another recipe (see "tips," below). Add 1 scant cup (113g) flour and 1/2 cup (113g) lukewarm water to the 1/2 cup (113g) starter in the bowl. Mix until smooth, return to its jar or crock, and cover.

, Repeat this process every 12 hours, feeding the starter twice a day. Remove starter to bake with as soon as it's expanded and bubbly, then feed the remaining starter immediately; revert to your normal 12-hour schedule for subsequent feedings.

Notice the bubbles in the starter on the right; this is 8 hours after feeding and it has expanded and become bubbly.

, To store your starter in the refrigerator: Take the starter out of the fridge; there may be a bit of liquid on top. Either drain this off or stir it in, your choice; it's simply a byproduct of the fermenting yeast.

, Spoon 1/2 cup (113g) starter into a bowl; either discard the remaining starter, or use it in another recipe (see "tips," below). Add 1 scant cup (113g) flour and 1/2 cup (113g) lukewarm water to the 1/2 cup (113g) starter in the bowl. Mix until smooth and cover. , Allow the starter to rest at room temperature (about 70°F) for at least 2 hours; this gives the yeast a chance to warm up and get feeding. After about 2 hours, replace the starter in its storage container and refrigerate.

, To maintain your starter's health (and for best baking results), repeat this process about once a week., To ready your refrigerated starter for baking: Take the starter out of the fridge, discard (or set aside) all but 1/2 cup (113g) and feed that 113g as usual with equal parts (113g each) flour and water. Cover the starter and let it rest at room temperature. Depending on its health and how recently you'd fed it, it will start to bubble and expand quickly, or may take up to 12 hours to show signs of life.

Our glass crock makes it easy to see how quickly your starter is expanding and monitor its growth.

, Feed the starter every 12 hours until you see it double or triple in volume within 6 to 8 hours; this means it's ready to bake with., For what you judge will be the final feeding prior to baking, add enough flour and water to use in your recipe, with 1/2 cup (113g) left over to feed and maintain the starter for the next time you bake. For instance, if your recipe calls for 1 cup (227g) starter, add 113g each water and flour. If your recipe calls for 2 cups (454g) starter, add 227g each water and flour.

, Once the starter is "ripe" (ready to use), spoon out what you need for the recipe and set it aside with the recipe's other ingredients. Feed the remaining 1/2 cup (113g) starter as usual, with equal parts (113g each) flour and water. Mix until smooth and let the starter rest for about 2 hours at room temperature before stowing it back in the refrigerator.
