A light, moist, and pillowy sandwich loaf made with a sweet stiff sourdough starter, Greek yogurt, honey, and a touch of instant yeast. Baked at a lower temperature to lock in moisture, it stays fresh and soft for days with virtually no sourness.
Dissolve 30 g sugar in 80 g water, then whisk in 60 g sourdough starter. Add 180 g bread flour, mix well, and knead into a firm ball.
Place in a jar, cover, and let ferment at 64°F (18°C) for 10–12 hours until tripled in volume.
Day 2: Mixing & Cold Fermentation (8:00 AM)
In stand mixer bowl, combine milk, Greek yogurt, sugar, honey, sweet stiff starter, dry instant yeast, and bread flour. Mix on low speed until a rough dough forms. (Note: No egg is needed).
Add 8 g salt and mix for 2 minutes.
Add 40 g softened butter, increase speed to medium, and knead for 10 minutes until smooth and elastic (must pass the windowpane test).
Cover and proof at 76–80°F (24–28°C) for 2–3 hours until puffy.
Transfer bowl to the refrigerator for overnight cold fermentation.
Day 3: Division, Pan Proof & Bake
Remove dough from fridge. Divide into 6 equal pieces and roll each into a tight cylinder.
Arrange 3 rolls side-by-side in each of two greased 9×4 inch baking pans.
Cover and proof at 80–84°F (28–32°C) for 2–3 hours until doubled in size.
Preheat oven to 350°F (175°C).
Load loaves into oven and immediately lower heat to 325°F (163°C). Bake for 25–28 minutes until golden brown.
Remove from oven and immediately brush tops with melted butter. Cool on a wire rack before slicing.
