I use (and sell) dried slices of galangale root and have no trouble powdering it. I put the slices into a Braun coffee mill and whizz it up. I then put it through a sifter and am left with a very fine powder with which to flavor galantynes or anything else. Sayyida Halima al-Shafi'i Stronghold of Raven's Cove www.lisasnaturals.com
