Hi Claire

we have a home flour mill and grind all our own flour .......

schnitzer are also a very good brand and I think they would be available in the USA chck out thie web site at http://www.schnitzer.com.au/ ( the Au $ is worth about 76c US so they would be cheaper )

my muffin receipe is below ........ it has milk but if you can use a milk substitute it may suit you

Single batch –18

2 cups brown rice flour ( 1.5 cups rice )
1/2 cup millet flakes
1 rounded teaspoon cream of tartar

200ml linseed meal choppd in food processor
