Equipment

  • Kitchen scale
  • Large mixing bowl (glass or stainless)
  • Banneton
  • Bread lame
  • Instant-read thermometer
  • Bench scraper
  • Cooling rack

Ingredients
  

Pumpkin Dough

  • 450 g bread flour or organic all-purpose flour
  • 50 g whole wheat flour
  • 250 g water room temperature
  • 100 g sourdough starter active and bubbly, at its peak
  • 225 g pumpkin puree plain canned pumpkin, not pie filling; room temperature
  • 10 g salt
  • 1 tbsp pumpkin pie spice store-bought or homemade

Cinnamon Swirl

  • 50 g brown sugar
  • 6 g ground cinnamon

Instructions
 

  • In a large bowl, mix all of the dough ingredients together (bread flour, whole wheat flour, water, sourdough starter, pumpkin puree, salt and pumpkin pie spice) until no dry flour remains. Cover.
  • Do 3–4 rounds of stretch and folds, about 30 minutes apart.
  • Cover and bulk ferment for 5–10 hours, depending on dough temperature (about 8–9 hours at 70°F). It's ready when it jiggles like Jell-O, has bubbles on the surface, and a gentle poke doesn't spring right back. If unsure, let it go a little more proofed rather than underproofed.
  • Stir the brown sugar and cinnamon together.
  • When the bulk ferment is fully done, turn the dough out and gently stretch it into a rectangle. Sprinkle the brown sugar and cinnamon evenly over the top.
  • Fold the dough in thirds toward the middle (a three-fold), then roll it up into a log.
  • Dust a banneton with flour and place the dough in it seam side up. Cover and cold proof in the fridge overnight, 10–12 hours.
  • Place the Dutch oven, lid on, in the oven and preheat to 450°F along with the oven, about 10–15 minutes. Don't let it sit in the hot oven long after preheating, or the bottom of the loaf can burn.
  • Turn the cold loaf out onto parchment paper and score the top.
  • Use the parchment as a sling to lower the loaf into the hot Dutch oven. Place about 3–6 ice cubes around the outer rim, between the parchment and the pot wall, for steam.
  • Bake at 450°F for 30 minutes with the lid on, then remove the lid and bake 15 minutes more.

Notes

  • Cool at least 1 hour before slicing, or the inside will be gummy and not fully set.
  • Starter: use it at its peak, 4–8 hours after feeding (feeding it the night before works well).
  • Timing: bulk ferment 5–10 hours depending on dough temperature; cold proof 10–12 hours. Watch the dough, not the clock.
  • Storage: airtight glass container or cotton bread bag on the counter for 2–3 days.
  • Freezing: freeze whole or sliced, wrapped in beeswax wrap or in a freezer-safe glass container, for up to about 3 months. Toast slices from frozen, or thaw a whole loaf on the counter and warm at 350°F for 10–15 minutes.
  • Not tested gluten free.
  • Additional times: Cold Proof 10 hr (10–12 hr in the fridge); Cooling 1 hr minimum.
