If the entire bean, hulls and all are crushed together I don't think you could ever seperate
if they were crushed very much...I do not think the water method will work...
In that link, mine were whole beans and I was able to control the amount of breakage
easily in the mortar and pestle. I cannot imagine any chocolate maker wanting
the hulls in his nibs, so I am guessing that your crushed product may not contain the hull
portion of the bean...emphasis on GUESSING....you will be able to tell by tasting a portion
and if there is a difficult to chew component...like the shell on a pecan, then your product
is likely mixed hull and all...it would be VERY unpalatable and tough to chew...the
meat of the bean however, crushes readily...similar to the meat of an almond.
I am sure that I would not desire the hull portion in any beer.
