  • 500 grams Dried Corn Kernels


  • First, wash the kernels and spread them out on a flat surface.
  • Then use a food processor or grinder to turn the kernels into a fine powder.
  • Next, line a strainer with cheesecloth or another type of cloth napkin.
  • Place it over a large bowl or pan and put something heavy on top of it to press out the liquid overnight.
  • The next morning, spread and dry the paste in a tray under the sun till it is completely dry.
  • Finally, grind it until smooth like powder!


  • For a richer flavor, you can also lightly toast the corn kernels before grinding them. This will help to bring out the natural sweetness of the corn and enhance its nutty flavor profile.
  • Additionally, for a more evenly dried paste, it's important to turn the paste in the drying tray every few hours. This will ensure all sides of the paste get an equal amount of exposure to the sun.
