  • If you are not sure if the blade is sharp, you should test it. Take a paper and use the blade to cut it without exerting pressure.

  • Pick a few solid pieces of your rock salt.
  • Hook these pieces with your blander machine at the shell of your food processor. So, why pick the solid piece instead of the powdered ones? It’s because you require something that will create enough friction.
