How to Activate a Dehydrated Sourdough Starter: A Step-by-Step Guide

If you’ve recently acquired a dehydrated sourdough starter, you’re about to begin a journey with one of the oldest and most delicious methods of baking. This guide will walk you through each step, transforming a dormant starter into a bubbling, thriving culture ready to elevate your homemade bread, pancakes, or even pizza dough!

What You’ll Need

To bring your dehydrated starter to life, here’s what you’ll need:

• ½ oz dehydrated sourdough starter
• ¼ cup warm water (filtered or distilled preferred to avoid chlorine, which can inhibit yeast growth)
• ¼ cup unbleached all-purpose or bread flour
• A 1-quart glass jar (about 32 oz capacity)
• A lid or cloth cover to allow airflow
• A spoon or spatula for mixing

Step-by-Step Activation Process

Day 1: Hydrate the Starter

1. Combine the Starter and Water
   • In a clean 1-quart jar, add ½ oz of dehydrated sourdough starter with ¼ cup of warm water.
   • Stir until the dehydrated starter is fully dissolved. This rehydration step is essential to wake up the natural yeast and bacteria.
2. Add Flour and Mix
   • Add ¼ cup of flour to the jar and mix until it’s smooth and well-combined.
   • Loosely cover the jar with a cloth or lid to allow airflow—this will help encourage natural fermentation.
   • Let the mixture sit at room temperature for 12–24 hours. During this time, you might begin to notice some bubbles or a slight rise, signs that your starter is coming to life.

Days 2–7: Feed and Nurture Your Starter

From here on, you’ll feed your starter daily, which helps it develop into a strong, active culture. Each feeding encourages natural yeast and bacteria to flourish, creating the foundation for your sourdough.

1. Divide and Feed Daily
   • After the initial 12–24 hours, divide the starter mixture into two parts. Save half (about 2 oz, or ¼ cup) and discard the other half. You can use the discard in recipes that don’t require an active starter, such as pancakes or crackers!
   • To the remaining starter, add 2 oz (¼ cup) of water and 2 oz (¼ cup) of flour.
   • Stir well until smooth and cover loosely. Let it sit at room temperature for another 12–24 hours.
2. Repeat Daily Feedings
   • Each day, repeat the process of discarding half the starter and feeding it with 2 oz of water and 2 oz of flour.
   • Stir to combine and let it sit for 12–24 hours. Within a few days, you should notice more bubbles, a pleasant tangy aroma, and increased rising action.

By Day 5–7: Check for Activity

By the end of the week, your starter should be showing signs of life—consistent bubbles, an increased volume, and a distinct, mildly sour aroma. These signs indicate that your sourdough starter is nearly ready to bake with!

• A fully active starter should double in size within about 12 hours after feeding.
• If it isn’t doubling yet, continue the feeding process for a few more days until it’s reliably doubling and bubbly.

When Is My Starter Ready for Baking?

Your starter is ready to use in baking when:

• It doubles in size within 12 hours of feeding.
• It has a bubbly, active surface.
• It smells pleasantly tangy or fruity.

Once these signs are consistent, you have a fully active starter! Now you can:

• Use it immediately in your sourdough recipes, or
• Store it in the refrigerator if you plan to bake less frequently. Just remember to feed it weekly to keep it healthy.

Starter Maintenance Tips

1. Temperature Matters
   Keep your starter in a warm room (ideally 70–75°F). Cooler temperatures slow down activity, which might delay the process.
2. Adjusting Consistency
   The starter should have a thick, pancake batter-like consistency. If it’s too thick, add a bit of extra water; if it’s too runny, add a small amount of flour.
3. Smell and Texture
   A healthy starter has a pleasant tangy smell, with a bubbly, airy texture. If it smells unpleasant or shows no activity, you may need to restart the process.

Final Thoughts

Once activated, your sourdough starter is a living culture, ready to be used in a wide array of delicious recipes. Whether you’re baking a classic sourdough loaf or experimenting with flatbreads, pancakes, or even waffles, your starter brings a unique, artisanal flavor to each dish.

With this simple activation process, you’re now on your way to a lifetime of homemade sourdough adventures. Happy baking!

Here are delicious recipes to make the most of your sourdough discard, ranging from a classic artisan bread to fun treats like pretzels and pancakes!

Artisan Sourdough Discard Bread Recipe

Ingredients

• Water: 1 1/4 cup (295g)
• Active Dry Yeast: 2 1/2 tsp (or one packet, 7g)
• Salt: 2 tsp (10g)
• Sourdough Discard: 1 cup (255g)
• All-Purpose Flour: 4 cups (575g)

Instructions

1. Prepare the Yeast:
   • Warm the water to about 110°F (43°C). Add the yeast, stir, and let it sit for around 5 minutes until bubbly.
2. Mix the Dry Ingredients:
   • In a large bowl, whisk together the salt and flour.
3. Combine Ingredients:
   • Add the sourdough discard and yeast mixture to the bowl with the dry ingredients. Mix thoroughly using a large spoon or silicone spatula until you have a shaggy dough.
4. First Rise:
   • Cover the bowl with a lid or plastic wrap and let the dough rise at room temperature for about 12 hours.
5. Preheat the Oven:
   • The next day, preheat your oven to 450°F (232°C) with a Dutch oven and its lid inside.
6. Shape the Dough:
   • Transfer the dough to a lightly floured surface. Shape it into a ball by pulling the edges towards the center 4-6 times. Flip the dough seam-side down and gently pull it towards you several times, rotating after each pull to add tension.
7. Final Rise:
   • Place the shaped dough on a piece of parchment paper, cover it with a towel, and let it rise in a warm place for 30 minutes to 1 hour.
8. Score the Dough:
   • If desired, use a lame or sharp knife to slash the top of the dough.
9. Bake the Bread:
   • Carefully transfer the dough (with the parchment paper) into the preheated Dutch oven. Cover with the lid and reduce the oven temperature to 400°F (204°C). Bake for 30 minutes, then remove the lid and bake for an additional 20-30 minutes until golden brown.
10. Cool and Enjoy:

• Let the bread cool completely on a wire rack before slicing to preserve its texture.

Tips

• Adding Tension: For a fluffier, better-rising loaf, don’t skip adding tension when shaping.
• Yeast Tips: Use water around 110°F to avoid killing the yeast.
• Crusty Exterior: Baking in a Dutch oven helps achieve a crisp crust on your artisan loaf.

Sourdough Discard Soft Pretzels Recipe

Ingredients

Dough:

• 226g whole milk
• 75g sourdough discard
• 50g brown sugar
• 7g instant yeast (1 packet)
• 390g bread flour
• 28g unsalted butter, softened
• 8g salt

Baking Soda Bath:

• 20g baking soda
• 452g hot water

Toppings:

• 20g pretzel salt
• 42g unsalted butter, softened

Instructions

1. Prep:
   • Preheat your oven to 475°F (245°C). Line two 18×13-inch baking sheets with parchment paper.
2. Scald the Milk:
   • Heat the milk in a small saucepan to 180°F (82°C), or until small bubbles appear around the edges. Transfer the milk to a large bowl and let it cool completely before proceeding.
3. Make the Dough:
   • Whisk the sourdough discard, instant yeast, and brown sugar into the cooled milk until fully dissolved.
4. Mix the Dry Ingredients:
   • Add the bread flour and salt to the wet mixture, folding in the flour until it’s fully hydrated.
5. Incorporate the Butter:
   • Gradually knead the softened butter into the dough, one tablespoon at a time. The dough will absorb the butter, becoming less oily as you go.
6. Knead the Dough:
   • Turn the dough onto a lightly-floured surface and knead for 5-10 minutes until it is smooth and elastic.
7. Bulk Fermentation:
   • Shape the dough into a tight ball and place it in a lightly-oiled bowl. Cover with plastic wrap and let the dough rise in a warm place for 20 minutes. It should be slightly puffy but not doubled in size.
8. Preshape the Dough:
   • Turn the dough out onto a clean surface and divide it into 10 equal portions. Roll each portion into a ball, covering them with plastic wrap. Let them rest for 15 minutes.
9. Shape the Pretzels:
   • Take one piece of dough at a time and roll it into a 24-30 inch rope with tapered ends. Form the rope into a U shape, twist the ends twice, and fold them over to form the pretzel shape. Secure the ends by tacking them to the sides.
10. Chill the Dough:

• Place the shaped pretzels on a baking sheet and freeze for 10 minutes to firm up.

11. Baking Soda Bath:

• In a large bowl, dissolve the baking soda in the hot water. Submerge each frozen dough piece in the baking soda bath for 1 minute, then transfer to a wire rack to drain.

12. Bake:

• Return the pretzels to the parchment-lined baking sheets. While still wet, sprinkle pretzel salt on top. Bake for 10-15 minutes, or until golden brown.

13. Brush with Butter:

• Once out of the oven, brush the warm pretzels with softened butter.

14. Enjoy:

• These pretzels are best eaten fresh from the oven. Enjoy them on their own or with a side of mustard!

Storage:

• Store any leftover pretzels in an airtight container for up to 3 days.

Tips:

• Weight Measurements: For best results, use a kitchen scale to measure ingredients by weight. Volume estimates can be less accurate.
• Resting Dough: If your dough is too sticky, let it rest for a few minutes. You can also oil your hands and work surface to help with kneading.
• Resting During Shaping: If the dough springs back when rolling it out, let it rest for a few minutes before continuing. Don’t force it to stretch, as it may tear.

Sourdough Starter Pancakes Recipe

Ingredients

Dry Ingredients:

• 1 1/2 cups (190g) all-purpose flour, spooned and leveled
• 2 tbsp (24g) sugar
• 1/2 tsp fine sea salt
• 2 tsp baking powder
• 1 tsp baking soda

Wet Ingredients:

• 1 cup (240g) sourdough starter (discard or active)
• 2 large eggs
• 1 cup (240ml) milk (plus more as needed)
• 3 tbsp (42g) melted unsalted butter or oil (plus more for greasing the skillet)

To Serve:

• Pure maple syrup
• Fresh berries
• Powdered sugar

Instructions

Overnight Preparation (for thick, fluffy pancakes):

1. In a large bowl, combine the wet and dry ingredients except for the baking powder and baking soda. Whisk well, cover, and chill overnight.
2. The next morning, sift the baking powder and baking soda over the batter and whisk to combine. The batter should be thick, bubbly, and pourable. If it’s too thick, add milk 1 tbsp at a time until it reaches your desired consistency. Let the batter sit for 5 minutes to aerate, ensuring it’s bubbly and light.

For thin, fluffy pancakes:

1. Combine all ingredients together and chill overnight. No need to sift the leavening agents separately.

Same-Day Preparation:

1. Preheat the oven to 250°F (120°C) to keep pancakes warm.
2. In a large bowl, whisk together the dry ingredients. Add the wet ingredients and whisk gently until the batter is smooth with a few lumps.
3. Heat a 10-inch skillet (cast iron or non-stick) over medium-low heat and melt a small pat of butter to coat the pan.
4. Pour 1/3 cup of batter into the skillet. Cook for 1-2 minutes, adjusting the heat as needed. When bubbles appear on the surface and the edges puff up, flip the pancake and cook for another minute.
5. Place the cooked pancake on a sheet pan and keep warm in the oven. Repeat until all pancakes are cooked.

To Serve:

• Serve with pure maple syrup, fresh berries, and a dusting of powdered sugar. Enjoy warm!

Sourdough Discard Pizza Dough Recipe

Ingredients:

• 200g sourdough starter (discard)
• 7g instant yeast (optional)
• 280g water
• 20g honey
• 30g olive oil
• 500g bread flour
• 20g salt

Instructions:

1. Mix Wet Ingredients: In a large bowl, combine the sourdough starter, water, and honey (and instant yeast if using). Stir until the starter and honey dissolve into the water.
2. Add Dry Ingredients: Add the olive oil, bread flour, and salt to the mixture. Gently stir using a dough whisk or a knife until it forms a shaggy dough. Cover with plastic wrap and let it rest for 30 minutes. The dough may seem dry and shaggy, but that’s okay!
3. Knead the Dough: Transfer the dough to a clean surface and knead for about 10 minutes until it becomes soft, smooth, and elastic. If you prefer, you can use a stand mixer to knead the dough (see the recipe notes for instructions).
4. First Rise: Once the dough is ready, place it in a warm bowl (you can warm the bowl with water and then dry it to help speed up the process). Cover with plastic wrap or a damp tea towel. Let the dough rise until it has doubled in size. Timing can vary, but this can take about 1 to 2 hours, depending on the warmth of the environment.
5. Divide and Rest: After the dough has doubled, divide it into smaller dough balls (200g per pizza works well for a standard-sized pizza). Let them rest on the counter, covered with a tea towel, for 30 minutes to allow the gluten to relax.
6. Shape the Pizza Bases: When ready to shape, gently press each dough ball into a round pizza base using your fingers. To stretch the dough, lift it and use your hands to gently stretch the edges, letting gravity do some of the work. Avoid using a rolling pin to preserve the dough’s natural texture.
7. Preheat the Oven: Preheat your oven to 450°F (230°C). Make sure it’s fully hot before placing the pizzas inside.
8. Prepare for Baking: Place the shaped pizza dough onto pizza peels or baking trays. Add your favorite pizza toppings.
9. Bake: Bake the pizza in the preheated oven for 12–15 minutes or until the crust is golden and crispy, and the toppings are cooked. For the best results, use a wood-fired or gas pizza oven, where you can bake the pizzas in 2–3 minutes at 662°F–752°F (350°C–400°C).

Notes:

• Dough Ball Size: This recipe makes 5 x 200g dough balls, which will yield about 10-inch (25cm) pizzas. If you prefer larger pizzas, you can make fewer, larger dough balls (around 250g–300g each).
• Bulk Fermentation: If you’re using sourdough discard without commercial yeast, expect the dough to take longer to rise (about 1–2 hours for the first rise). To speed this up, place the dough in a warm, slightly humid environment (e.g., a microwave with the door ajar). If using yeast, the rise will be quicker.
• Oven Tips: If baking in a conventional oven, make sure it’s fully preheated to 450°F (230°C) for the best results.

Sourdough Discard Flatbread Recipe

Ingredients:

• 2 tbsp butter (or ghee, olive oil, or other cooking fat)
• 1 cup sourdough discard (unfed)
• 1/8 tsp salt
• Everything bagel seasoning (optional)

Instructions:

1. Heat the Skillet: Place a nonstick skillet over medium heat and add 1 tbsp of your chosen cooking fat (butter, ghee, olive oil, etc.).
2. Spread the Discard: Once the skillet is hot, pour 1/2 cup of sourdough discard into the pan. Use a spatula to quickly spread the discard, wiggling and spreading as you go, to form a circular shape.
3. Season: Before the top begins to set, sprinkle with salt and any additional seasonings you like, such as everything bagel seasoning.
4. Cook the First Side: Let the flatbread cook for 3-4 minutes, until the discard is fully set and the bottom is golden and crispy. Check underneath to ensure it’s browned before flipping.
5. Flip and Cook the Other Side: Flip the flatbread and cook for another 2-3 minutes until golden and crispy on the other side.
6. Repeat: For the next flatbread, repeat with the remaining butter and sourdough discard.
7. Serve: Serve hot and enjoy the crispy, flavorful flatbread!

Notes:

• How to Store: Keep leftovers in an airtight container in the refrigerator for up to 2 days.
• Reheating: Reheat in a toaster for a crispy result, or microwave for 15 seconds. Alternatively, warm in a 250°F (120°C) oven for about 10 minutes.
• Freezing: These freeze well for up to 2 months. Store them in an airtight container or freezer bag, with pieces of wax paper between flatbreads to prevent sticking.
• Cooking Fat: Butter is the best option for flavor and spreading in the pan, but ghee, olive oil, or coconut oil also work well.
• Cooking Equipment and Scaling: Use any size nonstick skillet you prefer. For a 10-inch skillet, 1/2 cup of sourdough discard and 1 tbsp of cooking fat is a good ratio. Scale the recipe as needed for more flatbreads.
