Put the ground paste in the pot and put it next to the pot (iron pot for pancakes). Jinao sometimes squats down, sometimes sits on a low bench, scoops a proper amount of paste on a corner of a big hammer with a spoon, and then spreads a thin layer of paste quickly and evenly with a jinao (a bamboo tool). It's really a pleasure to watch jinao's quick movements. If you are in front of you, you will also hear the sizzling sound when the pancake ribs drive the batter. The paste from the pancake ribs will generate a hot air, which will soon disperse. It is necessary to constantly push grass under pancakes and spread firewood evenly with fire sticks. Pancakes are delicious only if they are heated evenly. The fire under the tobacco is a knowledge: if the fire is too big, the pancakes will be scorched by the kang; The fire is too small, and the pancakes won't open on the tobacco. People who often bake pancakes can master these skills. When the heat dissipates, they can pry out a pancake rib from a corner of the pancake, and finally take a thin and round pancake from the pancake and eat it.
