Ingredients

Leaven* (see note)

Sourdough Sandwich

  • 438 g organic white bread flour
  • 25 g sugar
  • 8 g salt
  • 285 g bottled or filtered water
  • 88 g leaven
  • 56 g unsalted butter, at room temperature
  • egg wash (1 large egg yolk + 1-2 tablespoon milk)
  • 14 g unsalted butter, melted

Instructions

Prepare the leaven

  • Combine the sourdough starter, water, and flour and stir until no lumps remain. Let sit in a warm spot (68-75°F / 20-24°C) until it has risen by about 75% and passes the float test, about 6 hours.

Prepare the dough

  • In a large bowl, using an electric mixer fitted with a hook attachment, add the flour, sugar, salt, water, and leaven, and knead on low speed until it comes together about 3-4 minutes. Scrape down the sides of the bowl halfway through. Let rest for 20-30 minutes.
  • Knead on low speed and gradually add the butter until it is completely incorporated. Once all of the butter is incorporated, increase the speed to high and knead for about 5-6 minutes until the dough is smooth, releases from the sides of the bowl, and passes the windowpane test. It's a soft, smooth, and satiny dough that is slightly tacky to the touch.
  • Lightly spray a straight-sided container with oil and transfer the dough to the container; lightly oil the top of the dough as well. Cover and let rest at room temperature for 12-15 hours until it has at least doubled, is full of small bubbles and wobbles like jellyfish when you gently shake the container. 
  • Spray an 8x4-inch (20x10cm) loaf pan lightly with oil or grease with butter and set aside. Also, turn on the light in the oven to create a warm environment for the dough to rise a second time. Between 75-80°F (24-27°C) is ideal.
  • Remove the dough from the container with a dough scraper, place it on a floured work surface, and flour the top of the dough. Roughly shape the dough into a square and deflate the dough with your fingers to pop the medium and large bubbles. That is important to create a fine and soft bread crumb. If needed, use more flour to prevent the dough from sticking, but be careful not to work more flour into the dough as necessary.
  • Then shape the deflated dough into a rectangle that is about 8-inch (20cm) wide and 10-inch (25cm) long. Starting from a short side, roll up the dough tightly and deflate it even further as you roll it up.
  • Transfer the dough to the prepared loaf pan and let rise in the warm oven for about 1.5-2 hours or until it has grown by about 50-75%.
  • Remove the dough from the oven and preheat the oven to 400°F (204°C) for 15-20 minutes.
  • Brush the dough with egg wash and bake for 30-35 minutes until the top is golden brown and it sounds hollow when you knock on the bottom of the sandwich. 
  • Remove from the oven, brush immediately with the melted butter and cover with a clean and dry kitchen towel for 20 minutes. Then uncover, remove the sandwich from the pan and transfer to a cooling rack to cool completely. Store in an airtight container at room temperature for up to 4 days.

Notes

* I feed my sourdough starter in a ratio of 1:5:5, 1 part starter, 5 parts flour, and 5 parts water and it doubles in about 6 hours. If you feed your starter in a different ratio (1:4:4 for example), I recommend preparing the leaven in the ratio you would normally do because it has to be strong enough to double in about 6 hours. Otherwise, the leaven may not grow as expected and the loaf may not rise properly.
