You can also buy Lorann Cotton Candy (which is Ethyl Maltol) locally at Hobby Lobby or a specialty cake supply store. I got 2 dram bottles of it for ~$2, this is what I use for sweetening my juice.
I sometimes buy a few Lorann flovars at Hobby Lobby, but never thought about getting ethyl maltol there. Is it sold as ethyl maltol or a differant name?
