                                1.
                                Make a Polish seed a few hours in advance: put high-gluten flour, dry yeast, and cold water into a bowl;

                                Mix well, cover with plastic wrap, ferment in a warm and humid place, or ferment at room temperature for 30 minutes and then transfer to the refrigerator for refrigerated fermentation;

                                When the volume is three times the original size, the inside is filled with large and small pores. This is a Polish starter;
                                    
                            
                            
                                4.
                                Polish seed starter and main dough materials are ready: the amount of sugar is too small, the amount can be adjusted according to taste; now it is hot, water and eggs can be used after refrigeration;

                                All the ingredients except butter are put into the kneading bucket;

                                Beat at low speed to form a dough, then turn to medium speed to make the dough smooth, add butter when the thick film can be pulled out;

                                Fully blend the butter into the dough at low speed, and turn to medium speed to make the dough smooth and soft with a decimal point, which can hold out a transparent and elastic film;

                                Round the dough and place it in a basin. Put the Mongolian plastic wrap on a warm and humid place for basic fermentation; now it’s hot, just leave it at room temperature for fermentation;

                                When the dough is twice as large, dip your fingers in flour and poke a hole on the top of the dough without collapsing or shrinking slightly;

                                Pour the dough on the operating table, weigh it and divide it into 9 equal parts, knead the dough separately, let the cling film relax for about 15 minutes, and press the dough with your fingers to relax in place without rebounding;

                                Roll the loose dough with the smooth side up and roll it into an oval shape; then turn it over so that the smooth side is facing down, and spread the floss on 1/2 of the dough;

                                Fold the dough sheet in half, and the smooth surface becomes the surface; press the edge with the palm to make the dough sheet stick firmly;

                                Use scissors to cut 4 knives on the curved edge, and each knife can be cut to the filling, so that natural cracks can appear during the second hair and baking;

                                The raw bread yards are placed in the baking tray, leaving room for expansion; placed in the oven for the second fermentation, you can put a bowl of water, and the temperature is adjusted to about 35 degrees;

                                When the green body is 1.5 times the original size, brush a layer of egg liquid on the surface; preheat the oven up and down to 180/190 degrees;

                                Put the bread into the middle and lower floors of the preheated oven, and fire up and down for 180/190 for 15 minutes. After the bread is out of the oven, it will be dried on a rack to hand temperature, and then put in a bag for storage.
                                    
                                         
                                         
                                     
                            
                            
                                Tips: 
                                1. Polish species can be fermented at room temperature or refrigerated to ferment, but it should not exceed 14 hours to prevent excessive fermentation and affect the taste; the amount of Polish flour is generally 25% of the main dough flour, with a slight fluctuation, but It is not advisable to have too much ratio to prevent the formation of dough strength; Polish seeds can delay the aging speed of bread, and it will not be hard after 3 days;
 2. The water absorption rate of flour and the environmental humidity during kneading are different. The new good top-baked Japanese bread flour I used has a high water absorption rate, so the amount of water in the formula can be reserved for 20 grams, depending on the state of the dough. Adjustment;
 3. The meat floss used in the filling is ready-made meat floss, the amount and the variety of filling can be adjusted according to the taste, such as jam, cheese filling, etc.;
 4. The baking temperature and time are adjusted according to the size of the bread, the actual situation of the oven used and the material of the baking pan.
