70% Hydration Sourdough Bread
A 70% hydration level is the sweet spot for home bakers. It provides enough moisture to secure an open, soft crumb structure, while keeping the dough firm enough to easily handle and shape into beautiful boules.
Dough Ingredients
Starter water or flour exceeds the total allowed recipe limits. Please adjust weights.

How it works: The sourdough starter consists of pre-fermented flour and water. To keep your recipe hydration exactly at target, we isolate these fractions and subtract them from your main flour and water additions.
Dough Ambient Temp & Proof Estimator
Fermentation speed is highly dependent on ambient kitchen temperature
Standard bulk rise time for sourdough. Watch for a 30-50% growth in volume before shaping.

Stay on schedule for gluten-building fold intervals
Methodology
This method is optimized for typical kitchen temperatures (72–76°F / 22–24°C). The 70% hydration formula utilizes a 20% prefermented flour ratio (100g sourdough starter at 100% hydration relative to 500g total flour), which ensures a steady bulk fermentation time of 4.5 to 5 hours.
Mix the adjusted flour (425g) and adjusted water (275g) in a large bowl. Let stand for 45 minutes. Dimple in the 100g starter and 10g salt. Squeeze the dough to incorporate.
Perform 4 sets of Stretch & Folds. Do a set every 30 minutes. You will notice the dough transitioning from a shaggy paste to a smooth, shiny, elastic mass.
Pre-shape into a loose round. Rest on the counter for 20 minutes (bench rest). Do the final shape to create surface tension, dust with rice flour, place in your proofing basket, and store in the fridge overnight.

Step 1: Stretch & Fold
The foundation of no-knead sourdough. Reach down to the bottom of the bowl, grab one quadrant of the dough, gently lift it upwards until you feel resistance, and fold it over the center. Rotate the bowl 90 degrees and repeat for all four sides.
