What to Do

• Mix the plain flour and strong flour together.
• Chop the butter into pieces and add it to the flour. Mix the flour and butter together by hand, gently rubbing them until combined.
• Add water, and continue mixing by hand until a dough forms. Wrap the dough in plastic wrap and refrigerate for 30 minutes.
• Roll the dough into a large sheet, then fold it into thirds. Refrigerate again for 30 minutes. Repeat this step two more times.
• Roll the dough out into a large sheet again, then sprinkle with sugar. Roll the dough inward from both sides, with one side slightly larger than the other. Freeze for another 20 minutes, pressing the sugar lightly to help it adhere to the dough.
• Cut the rolled dough into pieces to form butterfly shapes.
• Sprinkle more sugar on top before baking.
• Preheat the oven to 240°C (464°F) for 3 minutes. Bake at 160°C (320°F) for 20 minutes. (Every oven is different, so you may need to adjust the time and temperature to suit your oven.)
