The Perfect Summer Bake: Green Olive & Olive Oil Sourdough (And How to Beat the Heat)

When summer temperatures soar, baking sourdough can turn into an unpredictable guessing game. High ambient heat accelerates fermentation, weakens the gluten network, and risks leaving you with an over-proofed, sticky puddle before it even hits the oven.

Today, we are sharing a masterclass formula designed precisely to tame the summer heat while delivering a loaf packed with Mediterranean soul: a Buratto No. 2 Sourdough with Green Olives and Extra Virgin Olive Oil.

If you want to master the technical tricks for managing warm-weather dough and balancing inclusion salinity, read on!

The Formula (Based on 500g Flour)

Here are the precise measurements and baker's percentages used for this specialty loaf:

• Buratto No. 2 Flour (Type 2 / Half-White): 500 g (100%) – Provides a rustic aroma and incredible crumb texture.

• Ice-Cold Water: 350 g (70%) – Your secret weapon against high ambient heat.

• Active Sourdough Starter (Liquid Levain): 150 g (30%) – For a robust, energetic fermentation.

• Extra Virgin Olive Oil: 25 g (5%) – Softens the crumb and delivers an unmistakable fragrance.

• Fine Sea Salt: 10 g (2%) – Slightly reduced. Let's look at why.

• Green Olives (Pitted & Chopped): 100 g (20%)

  
  
  
  

Grazia's Tips: Managing Heat and Salinity

Behind this seemingly simple recipe lie two crucial technical adjustments that will transform your warm-weather baking:

1. The Cold Autolyse (The AC for your dough)

When your kitchen is hot, starting your mix with room-temperature water is an invitation for uncontrolled, runaway fermentation. The solution? A cold autolyse. By mixing all of your Buratto flour with ice-cold water and letting it rest for 45 to 60 minutes, you drastically drop the core temperature of the dough. This allows the gluten to develop cleanly and structurally before the yeast action even begins.

2. The "Deceptive" 2% Salt Rule

If you have an analytical eye for formulas, you probably noticed that 10 grams of salt for 500 grams of flour sits right at 2%. Usually, when a loaf is packed with salty inclusions, bakers drop the base salt even lower. Why keep it at 2% here? Green olives bring a massive amount of natural brine and sodium into the dough matrix. By locking the formula's added salt at 10g, we hit a perfect equilibrium: the final bread is flavorful and complex without ever crossing into "too salty" territory, keeping the gluten elastic and the taste perfectly balanced against the rich olive oil.

Step-by-Step Workflow

1. The Autolyse: Mix the ice-cold water with active starter, add the flour; let rest for one hour.

2. Inoculation: Add the salt, and olive oil, mixing until the dough is smooth, fully emulsified, and elastic.

3. Adding the olives: After an initial 30-minute rest, stretch the dough out on a damp counter and evenly scatter your chopped (and thoroughly patted dry!) green olives. Fold the dough back into a neat package.

4. Controlled Bulk Fermentation: Perform 3 to 4 sets of stretch-and-folds every 30 minutes. Keep a close eye on it—heat speeds things up! As soon as the dough looks airy, domed, and alive, it’s time to shape.

5. The Cold Retard: Once shaped into a boule or batard, place it in a dusted banneton and move it immediately into a 4°C refrigerator for 12 to 16 hours. This cold crash halts over-fermentation while unlocking deep, complex flavors.

   
   

The next morning, turn the cold dough out, score it cleanly down the center, and bake inside a preheated Dutch oven at 250°C with the lid on for 20 minutes. Remove the lid, drop the heat to 220°C, and finish for another 20–25 minutes. The aroma of toasted olive oil filling your kitchen is absolutely unmatched.
