I have had great success grinding things like rice, millet and quinoa in my now seldom used coffee grinder. I don't know if this will hold up day after day but so far it makes really fine powder out of most of the grains I've tried it with. The volume is small for each grinding but when multi-graining it works out great. I have not tried nuts yet. I would expect the oils might grease things up just like coffee does in a way, just perhaps a little more but it's like the other grains sort of help to clean it up in the end so when doing it I might try to figure on a greasiest to driest grind sequence. My own waffle day has things like soy powder, oatmeal, spelt, quinoa millet, and rice in the mix. I do use either baking powder or baking soda and arrow root powder. Lately I've been saving the boiling water from making rice pasta as the main liquid. I still use eggs,honey and olive oil. I think the ahead of time advice is a good idea for the batter but I think the baking soda might have to be added again along with the water. Finally adding water in the end and during the cooking can help bring the heaviness away and if one can go through the most helpful step of separating the eggs whites and whipping these to be "folded" in to the batter you can have the most light and fluffy anything! The griddle must be well up to the right temperature to have a drop of water "dance" across the top and vaporize. It's hard to wait to pour the first one till the griddle is really ready but it just must be.

I received this in an e-mail this morning, but remember it from many years ago, and liked it quite well, then.

I had forgotten about making cottage cheese pancakes decades ago! Thanks for reminding us, geminisue!
