Separating seeds from chaff
Do people have any tips besides what is commonly stated (e.g. winnowing, blowing the chaff away). What is your standard technique?
For now my standard technique is to put everything on an old wooden kitchen cutting board, slope it gently, and let the seeds roll down. The finer chaff tends to be slower and stick to the board, and the larger chaff is easy to separate by hand from the seeds. I repeat this four or five times. For certain seeds however this is not sufficient, and I wonder if you have good suggestions. I haven't used the method of blowing away the chaff yet -- it just occurs to me though that I could put everything in a fine sieve, tilt it, and blow through it; this should cause some separation.
