Hello, there is no need to add alkali. The formula of sesame seed cake (cylinder furnace, hanging furnace and iron plate) is: superfine powder 10 kg, yeast 100 g, crispy noodles 50 g, baking soda 50 g, sugar 150 g, ethyl maltol 2 g and water 5.5 kg. Technology: put the above raw materials into dough and ferment for 30-50 minutes (normal temperature fermentation 1-2 hours). Then the dough is divided into 150- 160g, and after kneading, it is divided into two kinds of dough, one of which is coated with seasoning liquid made of spiced powder, edible salt and maltol. Knead into dough, dip your hands in water, slice, brush with syrup, sprinkle with sesame seeds and bake in the oven.
