GIARDINIERA SOURDOUGH LOAF
Patience is key…
Ingredients:
100 grams of active bubbly starter
375 grams of warm tap water
500 grams of King Arthur bread flour
1 cup of giardinera hot peppers with oil (Marconi or Mezzetta)
9 to 12 g (1.5 – 2.5 teaspoons) fine sea salt
Directions:
Stretch & Fold Phase
After mixing the dough and letting it rest for 30 minutes:
Wet your hands slightly.
Grab one edge of the dough, stretch it upward, and fold it into the center.
Rotate the bowl 90 degrees and repeat.
Continue until you have completed 4 folds around the entire dough ball.
Cover and rest for 30 minutes.
Repeat this process 3 more times (4 total stretch-and-fold sessions, each 30 minutes apart).
During the third stretch-and-fold session, gently add the giardiniera and some of its oil. Distribute it throughout the dough as you perform the folds.
Bulk Fermentation
After the final stretch-and-fold:
Cover the bowl tightly. Let the dough rise at room temperature for approximately 8–10 hours (less in a warm kitchen).
The dough is ready when:
It has increased by about 50–75% in volume.
Small bubbles appear on the surface.
The dough jiggles when you gently shake the bowl.
Do not rely solely on time—watch the dough.
Preshape
Turn the dough onto a lightly floured work surface.
Gently shape it into a loose round.
Let it rest uncovered for 20–30 minutes.
This step allows the gluten to relax and makes final shaping easier.
Final Shape
Fold the top edge of the dough toward the center.
Rotate the dough slightly and repeat.
Continue working your way around the dough until a tight ball forms.
Use a bench scraper to pull the dough toward you across the counter, creating surface tension.
Cold Proof
Place the dough seam-side up in a floured banneton or towel-lined bowl.
Cover tightly.
Refrigerate for 12–48 hours.
For best results: Cold proof for at least 24 hours. This develops flavor and creates a lighter, more open crumb.
Baking
Place a Dutch oven with its lid in the oven.
Preheat for at least 45 minutes at 500–550°F.
Turn the dough onto parchment paper.
Score the top with a razor blade or sharp knife.
Transfer the dough to the hot Dutch oven.
Add 2–3 ice cubes between the parchment and the side of the pot (optional, but recommended for extra steam).
Cover immediately.
Bake:
30 minutes covered at 450°F
Remove lid
Bake 10–15 minutes more at 400°F until deep golden brown
For an extra-crispy crust, remove the loaf from the Dutch oven and bake directly on the oven rack for the final 5–10 minutes.
Cooling
Cool completely on a wire rack for at least 1 hour before slicing.
Cutting too early can result in a gummy interior.
For a giardiniera sourdough specifically, I'd recommend a 24-hour cold proof and 2–3 ice cubes in the Dutch oven—those two changes will give you the biggest improvement in flavor, oven spring, and crumb structure.
Notes
It’s super hard. Have patience.
Doing a cold proof for at least 24 hours before baking, which produces a lighter airier crumb.
Preheat your Dutch oven for a crisper crust.
Add ice cubes into the Dutch oven for a steamy loaf.
