To make Dry Chutney Powder using roasted peanuts, we need to grind the peanuts into fine powder. I have been trying to use the Vitamix blender to achieve the powder consistency, but no luck so far. At low variable speed the peanuts are just chopped, but as I increase the speed, the semi ground peanut mixture seizes up to form the butter, which is not what I want. I have used the regular jar, as well as the dry grind jar, but no luck so far. The resulting chutney powder has coarse, chunky peanut bits in them. Taste wise its good, but not the final product that I have in mind, especially with such an expensive blender and its accompanying jars. Has anyone tried this before?
