Kouign-Amann

Instructions

1. 1
   In a large bowl, dissolve the active dry yeast in warm water. Incorporate the bread flour and fine sea salt, kneading for 5-7 minutes by hand or stand mixer until a smooth, pliable dough forms. Cover and let rise at room temperature for 1 hour until doubled.
2. 2
   Punch down the dough, press it into a neat flat square, wrap tightly in plastic film, and chill in the refrigerator for 30 minutes to slow the yeast activity.
3. 3
   Beat the cold butter block with a rolling pin between two sheets of parchment paper until it becomes a malleable, uniform 14x14 cm square sheet. Keep cool.
4. 4
   Roll out the cold dough on a lightly floured surface into a 22x22 cm square. Place the butter sheet diagonally in the center like a diamond, then fold the dough corners inward to seal the butter completely inside like an envelope.
5. 5
   Gently roll the envelope lengthwise into a long rectangle. Fold the dough in thirds like a letter. Rotate 90 degrees and repeat: roll longwise and fold in thirds again. Wrap in plastic and chill for 30 minutes (completing the first two traditional dry turns).
6. 6
   Remove dough from the fridge. Now for the crucial phase: generously dust the counter and the dough surface with one-third of your granulated sugar. Roll the dough into a long rectangle directly over the sugar, forcing the crystals into the layers. Fold in thirds. Rotate 90 degrees, add more sugar, roll, and fold in thirds again. The dough will become sticky from the dissolving sugar.
7. 7
   Roll the dough a final time into a 25x25 cm square. To build the large iconic coiled shape seen in `Kouign-amann.png`, shape the dough into a tight circular swirl or tuck the corners inward loosely toward the center core.
8. 8
   Place the pastry inside a round cake tin or pastry ring that has been heavily greased with butter and coated in the remaining sugar (this creates the exterior candy coat). Let rest for 20 minutes at room temperature.
9. 9
   Preheat your oven to 190°C (375°F).
10. 10
    Bake the Kouign-amann for 30-35 minutes. The butter will bubble intensely as the sugar transforms into a deep mahogany syrup.
11. 11
    CRITICAL STEP: Allow the pastry to cool inside the pan for only 3 minutes. Invert it immediately onto a wire cooling rack. If left to cool completely inside the pan, the caramel will harden into stone-like candy, permanently welding the pastry to the tin.
12. 12
    Let cool completely on the rack so the exterior glaze solidifies into a shattered-glass crispy texture identical to the reference photo before slicing open to reveal the moist interior.
