Raw materials: Choose millet that is free from insects, mildew, and good color, and wash it with clean water to remove impurities.

Pulverizing: Soak the millet in water for 2 to 3 hours, dry it, grind it into a fineness of more than 80 mesh, and dry it.

Mixing and stirring: Add an appropriate amount of flour to the millet flour to increase the viscoelasticity of the dough. The addition ratio is 1:1. Pour into the mixer and add milk powder, refined salt, sugar, vegetable oil, and eggs in sequence, and stir. Evenly, then add the syrup, finally add a small amount of salt and baking soda, and stir for about 10 minutes.

Forming: Put the mixed dough into the roller printing biscuit machine and roll it into shape.

Baking: Put the formed raw biscuit base into the oven at a temperature of about 220°C, and bake for 5 to 10 minutes.
