Ingredients
Method
- 1: Mix the dough: In a large bowl, whisk 150 grams plain whole milk kefir, 200 grams water, and 100 grams active sourdough starter together. Add 500 grams bread flour. Mix until no dry flour remains. Cover and rest 30 minutes (autolyse).
- 2: Add salt: Sprinkle 10 grams fine sea salt over the dough. Pinch and fold until fully worked in. Cover and rest 30 minutes.
- 3: Stretch and fold: Do 2 sets of stretch and folds, 60 minutes apart.
- 4: Add cheddar and jalapenos: Toss 150 grams sharp cheddar cheese, shredded and 80 grams pickled jalapenos, drained and diced in 1 tablespoons extra flour for tossing add-ins. Press the dough into a rectangle, scatter on the cheese and jalapenos, then fold and do one more stretch and fold to distribute evenly.
- 5: Bulk ferment: Cover the dough and let it rise at room temperature until it grows by about 50%. This takes 4 to 270 minutes depending on how warm your kitchen is.
- 6: Shape the loaf: Turn the dough onto a lightly floured surface. Shape into a round or oval loaf. Place seam-side up in a floured banneton or bowl lined with a towel.
- 7: Cold retard overnight: Cover the banneton and place it in the fridge for 8 to 480 minutes. This builds flavor and makes the dough easier to score.
- 8: Preheat and score: Preheat your oven to 450°F (230°C) with a Dutch oven inside for 30 minutes. Turn the cold dough onto parchment paper (this catches any leaking cheese). Score the top with a sharp blade.
- 9: Bake: Place the dough into the hot Dutch oven with the lid on. Bake 45 minutes covered, then remove the lid and bake 20 to 25 minutes more, until deep golden brown.
- 10: Cool completely: Move the loaf to a wire rack. Let it cool for at least 60 minutes before slicing. Cutting too early makes the inside gummy.
Notes
Shred your own cheddar instead of using pre-shredded bags, pre-shredded cheese has anti-caking additives that keep it from melting smoothly into the dough. Drain and pat the jalapeños dry so they don't add extra moisture. Store the baked loaf at room temperature for up to 2 days, or freeze sliced for up to 3 months.
