8:00 AM: In a small glass jar, dissolve your 10g of starter culture into 30g of water. Whisk together cleanly, then stir in 30g of bread flour. Mix thoroughly, cover loosely, and let it ferment at room temperature 74–78°F (23–26°C) for roughly 6 hours until it at least triples in volume.
2:00 PM – The Autolyse: In the bowl of your stand mixer, combine the 80g of water, 60g of active starter, 1 large egg, 80g of sugar, and the optional 1g of dry yeast. Whisk together, then dump all 250g of bread flour on top. Mix until a shaggy mass forms with no dry spots, cover, and let autolyse for 30 minutes.
2:30 PM: Attach your dough hook. Mix the dough on low speed for 2 to 3 minutes (or on a KitchenAid mixer on speed 3 for 3 to 4 minutes) until cohesive. Sprinkle in the 5g of salt and mix for 2 more minutes until a firm ball gathers around the hook.
The Fat Incorporation: Turn your machine to high speed and drop in the 25g of soft butter (or lard). Knead continuously for 7 to 10 minutes until the fat incorporates seamlessly and the dough clears the sides of the bowl beautifully. Cover and let rest for 1 hour at a warm 76–80°F (24–28°C). Perform exactly 1 round of structural stretch-and-folds during this rest.
3:30 PM – The Paper-Thin Hand Stretch: Lightly coat a very large workspace with a neutral, flavorless oil. Place the dough in the center and use your hands to flatten it out until it is roughly 4 to 5 mm thick.
Gently spread all 200g of your ultra-soft laminating butter across the entire surface of the dough sheet. Critical Guardrail: You must spread the butter onto the dough before you stretch it thin. Attempting to apply heavy butter to an already stretched, paper-thin sheet will slice and rip the delicate structure apart.
Once the butter is evenly spread, wet your hands and gently pull the dough from the center outward, stretching it across your counter as paper-thin and translucent as possible.
Starting from one edge, roll the thin dough sheet up tightly into a long, dense rope. Cover the rope and let it sit undisturbed for 30 minutes to relax the gluten.
4:00 PM – The Snail Spiral Shape: Gently pull and stretch the rolled rope lengthwise until it becomes longer, evenly shaped, and tapers down to roughly 2 to 3 cm in diameter.
Line a large tray with parchment paper. Arrange the elongated rope into a classic coiled snail shape (spiral), ensuring you leave a clear 2 cm gap of empty space between each spiral layer to allow room for growth.
Cover loosely and let proof at a warm room temperature of 74–78°F (23–26°C) for 3 hours.
7:00 PM: Move the tray into a cooler room or proofing area sitting at a steady 64–68°F (18–20°C) and allow it to proof slowly overnight until the next morning.
