This detailed guide will walk you through every step, from understanding the starter to baking and storing your bread, while addressing common questions and incorporating essential tips for success.

What is King Arthur Sourdough Starter?

A King Arthur sourdough starter is a simple yet magical mixture of flour and water that captures wild yeast and beneficial bacteria from the environment. This fermented blend acts as a natural leavening agent, giving sourdough bread its rise and distinctive tangy flavor. King Arthur recommends using their high-quality unbleached bread flour (with 12.7% protein) for optimal fermentation, though all-purpose flour can work in a pinch. The starter is created by combining equal parts flour and water (by weight, e.g., 113g each) and letting it sit at room temperature for 24 hours to kickstart fermentation. Over 5–7 days, with regular feedings, it develops into a bubbly, active starter ready for baking. You can make your own or purchase King Arthur’s fresh sourdough starter, which is descended from a New England strain nurtured since the 1700s, ensuring vigorous performance right out of the box.

How to Make King Arthur Sourdough Bread

Baking sourdough bread with the King Arthur recipe is straightforward, especially with their beginner-friendly No-Knead Sourdough Bread or Rustic Sourdough Bread recipes. Here’s a step-by-step guide based on the classic King Arthur approach:

Ingredients:

• 1 cup (227g) ripe King Arthur sourdough starter (fed and doubled in volume)
• 1 ¾ cups (397g) lukewarm water
• 5 cups (600g) King Arthur Unbleached Bread Flour
• 1 tablespoon (18g) salt
• ½ cup (60g) King Arthur Whole Wheat Flour (optional, for added flavor)
• 1–2 teaspoons instant yeast (optional, for a faster rise, especially for beginners)

Instructions:

1. Mix the dough: In a large bowl, combine the ripe starter, water, and flours. Stir until a sticky, rough dough forms. Let it rest for 20 minutes (autolyse) to hydrate the flour.
2. Add salt and knead: Sprinkle in the salt (and yeast, if using). Knead by hand for 5–7 minutes or use a stand mixer with a dough hook for 3–5 minutes until smooth.
3. Bulk fermentation: Place the dough in a lightly greased bowl, cover, and let it rise for 1.5–6 hours, depending on your starter’s strength and kitchen temperature (about 70°F). Perform a fold every hour by stretching and folding the dough over itself to build structure.
4. Shape the dough: On a floured surface, divide the dough in half (for two loaves). Preshape into balls, rest for 15 minutes, then shape into boules or logs for your baking vessel.
5. Final proof: Place the shaped dough in a banneton or greased pan, cover, and let rise for 2–3 hours (or refrigerate for 12–48 hours for a tangier flavor).
6. Bake: Preheat the oven to 450°F with a Dutch oven or baking stone inside. Dust the loaf with flour, score with a lame or sharp knife, and bake covered for 45 minutes, then uncovered for 10–15 minutes until deep golden brown (internal temperature of 210°F).
7. Cool: Transfer to a rack and cool completely before slicing.

This recipe yields a chewy, crusty loaf with a rich flavor, perfect for sandwiches or toast.

How to Use King Arthur Sourdough Starter

Using your King Arthur sourdough starter effectively starts with ensuring it’s ripe and active. A ripe starter has doubled in volume, is bubbly, and shows signs of just beginning to sag (typically 6–8 hours after feeding). Here’s how to use it:

• For baking: Measure out the required amount (e.g., 1 cup or 227g for the recipe above) and add it to your dough ingredients. Feed the remaining starter to keep it healthy.
• For other recipes: Use ripe starter for pancakes, waffles, or crackers. Discard starter (the portion removed during feeding) can be used in recipes like sourdough pizza crust or chocolate cake to reduce waste.
• Tips for success: Always use a scale for accuracy, as volume measurements can vary. Ensure your starter is at peak activity before baking to guarantee a strong rise.

How Often to Feed King Arthur Sourdough Starter

The feeding schedule depends on how often you bake and where you store your starter:

• Room temperature (70°F): Feed twice daily, every 12 hours, with 113g starter, 113g flour, and 113g water (1:1:1 ratio by weight). This keeps the starter ready for frequent baking.
• Refrigerator: Feed once a week with the same 1:1:1 ratio. After feeding, let it rest at room temperature for 2–4 hours before refrigerating to activate the yeast.
• Infrequent baking: For less frequent bakers, refrigerate the starter and feed weekly to maintain its health. Before baking, give it 1–2 room-temperature feedings to revive its activity.

How to Refresh King Arthur Sourdough Starter

If your starter is sluggish or smells like acetone (a sign of neglect), refreshing it is simple:

1. Discard: Remove all but 50g of starter to reduce waste and focus on fresh feeding.
2. Feed: Add 50g bread flour and 50g lukewarm water (1:1:1 ratio). Stir until smooth and cover loosely.
3. Rest: Let it sit at 75–80°F for 6–12 hours until bubbly and doubled. Repeat for 2–3 days if needed to restore vigor.
4. Prevent contamination: Use clean utensils and a fresh jar for each feeding to avoid mold or off-flavors.

What Flour is Best for Sourdough Bread?

King Arthur’s Unbleached Bread Flour, with 12.7% protein, is ideal for sourdough due to its strength and ability to support robust fermentation and gluten development. For added flavor, incorporate 10–20% whole wheat or rye flour, but increase water slightly (by 10–20g) as these flours absorb more liquid. All-purpose flour (11.7% protein) can work but may yield a less structured loaf. Avoid low-protein flours like cake flour, as they lack the gluten needed for a good rise.

Can You Freeze King Arthur Sourdough Bread?

Yes, you can freeze King Arthur sourdough bread to extend its shelf life. Wrap the cooled loaf tightly in plastic wrap, then place it in a freezer bag. It can be frozen for up to 3 months. To enjoy, thaw at room temperature or reheat slices in a 350°F oven for 5–10 minutes to restore the crust’s crispness. Freezing is perfect for batch baking or preserving leftovers.

How to Store Sourdough Bread After Baking

To maintain freshness, store your sourdough loaf in a paper bag at room temperature for 2–3 days to preserve the crust’s texture. Avoid plastic bags, as they trap moisture and soften the crust. For longer storage (4–5 days), wrap the loaf loosely in a clean cloth or place it in a bread box. For extended storage, freeze as described above. Never refrigerate baked sourdough, as it can stale faster.

Why is My Sourdough Not Rising?

If your sourdough isn’t rising, consider these common culprits:

• Weak starter: Ensure your starter is active and doubles within 4–6 hours of feeding. If not, refresh it with 1–2 feedings before baking.
• Cold environment: Dough rises slower in cooler kitchens (below 70°F). Use a warm spot or a proofing box to maintain 75–80°F.
• Overmixing: Kneading too aggressively, especially with a stand mixer, can damage gluten structure, leading to dense bread. Mix gently by hand for best results.
• Incorrect hydration: Too much or too little water can affect rise. Weigh ingredients precisely, especially in humid conditions where flour absorbs less water.

Is King Arthur Sourdough Beginner Friendly?

Absolutely, King Arthur’s sourdough recipes are beginner-friendly. Their No-Knead Sourdough Bread and Easy Everyday Sourdough Bread recipes require minimal effort, with no kneading or complex shaping.
