What's the best electrical grinder to grind things like coconut, rice etc?
I am looking for a electrical grinder / electrical mill to grind desicated coconut, rice etc. Does anyone know what would be most suitable? I've used a mill on an electrical blender but it doesn't seem to work well. Would a coffee grinder do the job or do I need to buy something else? Thank you.
