Thousand-layer meringue --- -How to make butterfly puff pastry

1. Mix medium flour, water, salt and melted butter into a ball, then refrigerate to relax for more than 1 hour. It is recommended to refrigerate overnight. This dough does not need to be kneaded to be very smooth or stringy, it only needs to be formed into a ball, and the relaxation time must be sufficient. This is critical for the subsequent folding. Use a rolling pin to pound the flaky butter into thinner and larger pieces until it has good ductility. Use a knife to cut a cross on the surface of the relaxed dough, then roll it out along the sides, spread the thinly rolled butter in the middle of the dough, fold up the four corners, and pinch to seal.

2. Roll the dough wrapped with flaky butter into a long strip horizontally, fold in 3/8 of the left edge of the dough, and fold in 1/8 of the right edge of the dough. , and then fold the dough in half to complete the fourth fold. Turn the dough 90 degrees and roll it out again. Fold the left and right sides inward by 1/3 to complete a three-fold fold. After folding twice, put the dough in the refrigerator for more than 1 hour. Repeat the above steps one more time, folding the dough four times in one go, four folds, three folds, four folds, and three folds. After four folds, the dough is placed in the refrigerator for another 1 hour, then shaped and set aside.

3. Take out the refrigerated dough and roll it out to a thickness of 3mm. Use a sharp knife to cut off the corners. Take a 50cm long piece of puff pastry, brush it with a layer of water, sprinkle with fine sugar, and cut it about 1/2 from both sides. Fold 6 points inward twice, leaving a gap of about a finger in the middle. After thinning the gap, fold the pastry in half and press it tightly. Send it to the refrigerator to freeze for about 30 minutes, take it out and cut it into 8mm thick, and place it in a baking pan. Preheat the oven to 200 degrees, set the middle layer, and bake until the edges are browned, then turn over and continue baking until browned.
