A naturally leavened sourdough loaf baked in a bread pan, studded with sharp cheddar and finished with a soft, sliceable crumb—perfect for sandwiches.
Mix:
500 g flour
310 g water
Stir until no dry flour remains. Cover and rest for 30 minutes.
Add:
100 g active sourdough starter
10 g salt
Remaining 20 g water
Pinch and fold until fully incorporated and cohesive.
The dough will be tacky at this stage — do not add flour.
Perform 4 stretch and folds, spaced 30 minutes apart.
Use wet hands to prevent sticking
Dough should become smoother and stronger with each fold
After the final fold, allow the dough to rise undisturbed until:
About 50% increase in volume
Rounded edges
Slight jiggle when the bowl is shaken
Small bubbles visible along the sides
Lightly flour the counter
Gently turn out the dough
Stretch into a rectangle without aggressively degassing
Sprinkle cheddar evenly, leaving a 1-inch border
Fold bottom up, top down, then sides in
Roll into a loose log
Bench rest 20 minutes, uncovered.
Tighten the dough into a sandwich loaf shape
Keep all cheese fully enclosed
Place seam-side down into a parchment-lined loaf pan
Proof at room temperature until:
Dough crowns ½–1 inch above the pan rim
A gentle poke springs back slowly, not instantly
This typically takes 1 to 1½ hours.
Do not overproof
Preheat oven to 475°F (245°C)
Score loaf lengthwise with a shallow cut
Bake:
25 minutes at 475°F
Reduce oven to 425°F (220°C) and continue baking 20 minutes
Cool on a wire rack for at least 60 minutes before slicing.
Cutting early will result in a gummy crumb.
