Yes Michele, do bring your berries to room temp before grinding. There is actually no real reason to keep the berries themselves in the freezer, an airtight container works just fine. Once you have ground your berries into flour keep the flour in the freezer and remove a few hours before using so it has a chance to come to room temp.
Winnie- I only have experience with a big sized mill. We have the Country Living Grian Mill, which I highly reccomend if you have the room. The quality is great, customer service is excellente, and it is made in the USA. Wouldn't trade it for any other.
thanks Lillian, will do that. I have not had a chance yet to try grinding. Maybe today. I got the book Laurels Kitchen Bread Book, from the library. It has lots of good information. I have steel, and stone grinding plates. What would be best to use? Or maybe what is each to be used for? Sure wish I had gotten some directions with the grinder.
