STEP 1/9
Add salt to the sieve flour and soft flour and knead little by little with cold water.Just knead until you can see a little bit of raw powder.
STEP 2/9
Cover dough with plastic or plastic wrap and rest in refrigerator for 1 hour. Make a cross cut on the top of the tissue dough.
STEP 3/9
Spread the sheath and shape the dough into a square shape, then place the butter, a roll, on top of the dough.
STEP 4/9
Fold the dough into a card envelope, wrap it around the butter, and then connect the dough so that the butter is not visible. (Be careful if you don't connect the dough carefully, butter will flow out and it will be difficult to work.)
STEP 5/9
Dab the butter gently with a rolling pin and allow the butter to spread evenly over the dough. Slowly roll dough up and down, sprinkling flour to prevent butter from leaking out.
STEP 6/9
If it is nearly three times as long as the first dough, shake off the flour. Next, fold the dough into 3 pieces and let it rest in the refrigerator for 30 minutes. Turn the dough out of the refrigerator to 90 degrees in the direction it was first pushed, then push it up and down with extra flour to nearly triple it. Repeat this process three more times, then rest the dough in the refrigerator for 30 minutes.
STEP 7/9
Roll the dough 32cm wide and 18cm long, then sprinkle with chocolate chips and chopped walnuts.
STEP 8/9
Roll the dough tightly together. Then leave in the refrigerator for 10 minutes.Cut the dough out of the refrigerator into 6 pieces with a knife.
STEP 9/9
Place the cut dough in a baking cup or pan and bake in an oven preheated to 200 degrees for 15 to 20 minutes.
Use cold butter for butter, but if you work with butter that is too cold, the dough may tear when you roll. Cold butter, which is a little harder than the dough, is appropriate.
