Place your banana pieces in the blender, add a teaspoon of salt and slightly cover the mixture with warm water. The salt will help the DNA stay together during the mashing process. Mix in the blender for 5 to 10 seconds making sure the mixture is not too runny. Pour the mixture into the glass jar through the strainer.
