Next comes the shaping process. We refuse to use fillers such as sweet potato paste or starch, and instead insist on using powder made from five black ingredients as the core raw material. A small amount of drinking water and prebiotics are added for blending to form a uniform dough.

If it's too thin, it becomes prone to crumbling; if too thick, the texture turns overly hard. The 1.2-millimeter thickness ensures ultimate crispiness while allowing every bite to be filled with the substantial texture of the ingredients. The cut crisps are then sent to a constant-temperature baking chamber, where a "low-temperature slow-baking" process is employed instead of traditional deep-frying. The baking temperature is precisely controlled at 70℃ for a duration of up to 6 hours. By…
