Spread the flour evenly on the panel and flatten the fermented dough into a thin dough.
Soften 20 grams of butter and spread a layer on the entire dough
Stacked quilt, fold up again and flatten again, do it three times in a row
The last time it is made into a thin dough (if you like crispy, it will be thinner), cut into equal parts of the size of a common biscuit with a knife (you like it)
Put some small holes in a good aliquot and let stand for 15 minutes.
Press some cooked sesame on the biscuit, then sweep the brine
Oven 190 degrees, 20 minutes
