Mastering 100% Hydration Sourdough: Crystal Bread Tutorial

Understanding the Magic of 100% Hydration Sourdough

The world of sourdough baking is vast and varied, and one of the most intriguing aspects is experimenting with hydration levels. Today, we're diving into the realm of high hydration with a 100% hydration sourdough, also known as Crystal Bread, as demonstrated by Bread by Joy Ride Coffee. This technique may seem daunting at first, but with guidance and practice, it can become a rewarding part of your sourdough journey.

Ingredients and Preparation

To start, you'll need:

• 325g of water
• 325g of Manitoba Casillo flour (with 13% protein)
• 65g sourdough starter
• 7.5g salt

Begin by mixing the water and flour and allowing them to autolyse for one hour. This crucial step helps to develop the gluten network, making the dough more manageable despite its high hydration.

The Rubaud Method: Hand Kneading

After the autolyse, incorporate the sourdough starter using the Rubaud method, a gentle hand kneading technique. Allow the dough to rest for 30 minutes, then integrate the salt using the same method. The Rubaud method is perfect for high hydration doughs as it helps maintain the dough's integrity without tearing.

Mastering Coil Folds

Perform five coil folds at 30-minute intervals. This step strengthens the dough and builds its structure, crucial for high hydration breads. After completing the folds, let the dough bulk ferment at room temperature (22-23°C) for about 8 hours and 30 minutes.

Cold Fermentation and Baking

Once the bulk fermentation is complete, cover the dough and refrigerate it overnight at 4°C. In the morning, divide the dough into two portions and allow them to rest on baking sheets for an hour as you preheat your oven to 250°C.

Bake the dough on a baking steel at 250°C for 10 minutes with steam, then reduce the heat to 210°C and bake for another 20 minutes without steam. This process helps achieve a crispy crust and a beautifully open crumb.

Key Takeaways

• Autolyse helps develop gluten in high hydration doughs.
• The Rubaud method is ideal for gentle kneading.
• Coil folds build dough strength and structure.
• Cold fermentation enhances flavor and texture.

FAQs

• What is high hydration sourdough? High hydration refers to dough with a water content equal to or greater than the flour weight, resulting in a moist, open crumb.
• Why use the Rubaud method? It's a gentle kneading technique perfect for maintaining dough structure in high hydration recipes.
• How do coil folds help? They strengthen the dough without deflating it, crucial for maintaining structure in high hydration breads.
• What is the purpose of cold fermentation? It develops flavor and improves the dough's texture by slowing down yeast activity.
