10:00 PM – Stiff Starter Initialization: In a small glass jar, dissolve the 5g of sugar into 30g of water and whisk cleanly. Stir in your 8g of starter culture and 60g of bread flour. Mix thoroughly and knead by hand into a tight ball. Cover loosely and let it sit at room temperature 74–78°F (23–26°C) overnight for 8 to 10 hours until it more than doubles in volume. This low-hydration, sugary setup ensures low overall dough acidity.

8:00 AM – The Grand Autolyse: In your stand mixer bowl, combine all 75g of whole milk, 50g of sweetened condensed milk, 1 large egg, 20g of granulated sugar, 75g of your active overnight sweet stiff starter, and all 250g of bread flour (along with the optional 0.5g of dry yeast if using). Mix everything together with a heavy spoon just until a dense, sticky mass forms. Cover and let rest for 1 full hour to completely hydrate the flour proteins.

9:00 AM – Developing Gluten: Attach your dough hook. Mix the autolysed dough on low speed for 2 to 3 minutes (or use a KitchenAid mixer on speed 3 for 3 to 4 minutes) until well incorporated. Add the 5g of fine sea salt and continue mixing for an additional 2 minutes until the dough forms a tight, cohesive ball.

Butter Emulsification: Turn your mixer up to medium speed and gradually drop in the 50g of softened unsalted butter piece by piece. Once all the butter is introduced, increase the speed and mix continuously for 10 more minutes until the fat is completely emulsified, the dough clears the sides of the bowl, and it passes a clear, translucent windowpane test.

Bulk Proof with Intervals: Cover the container tightly and let it proof for 3 to 4 hours at a warm 76–80°F (24–28°C). During this window, perform 2 gentle rounds of stretches and folds to build structured vertical strength. The dough should look visibly lighter and slightly puffy.

1:00 PM – Cold Fermentation Stabilization: Slide the entire covered proofing container directly into the refrigerator to rest slowly for 6 to 9 hours of cold fermentation retard to chill the butter fats.

10:00 PM – Dividing the Portions: Remove the chilled dough from your refrigerator. Tip it onto a clean work surface. Using a bench scraper and a kitchen scale, divide the dough cleanly into 12 equal portions (roughly 47–50g each).

Tension Ball Shaping: Take a portion of dough, cup your hand over it, and roll it firmly against the counter in a circular motion to form a smooth, taut, uniform ball. Pinch any loose edges cleanly to the bottom. Grease a 9x9 inch baking pan with butter, and arrange the 12 shaped dough balls neatly inside.

The Overnight Counter Rise: Cover the baking pan loosely with plastic wrap or a damp kitchen towel. Let the rolls proof overnight on your counter for 8 to 10 hours at a stable room temperature of 70–74°F (20–23°C) until the next morning. They must completely double in volume, swelling until they look extraordinarily light, airy, and clustered.

7:00 AM – Baking: Preheat your home oven to 375°F (190°C). Dust the top crowns of your beautifully risen, clustered rolls lightly with a fine dusting of flour or coat them cleanly with an egg wash.

The Crisp Finish: Slide the pan onto the middle oven rack and bake for 30 to 35 minutes until the crowns turn a uniform, rich golden brown. Remove from the pan and allow them to cool slightly on a wire rack before pulling them apart to serve warm!
