Bread-Bakers v100.n071.19

My professional training is in hydrology but a soils class I took relates 
well to this question.  You mentioned that an ultra fine grind of sugar 
would have more sugar per cup than a large grind due to the fact that with 
the large grind each grain would take up more room.  I thought the same 
thing until one day in soils class we were presented with the same problem.

Except instead of sugar, we were discussing clay or sand.  The pore space 
of each "cup" of soil was the same, regardless of its 'grind'.  It didn't 
matter if it was clay or sand.  It would matter if you mixed the two 
because the clay could fill the pore space of the sand and result in a much 
less porous mixture.  Which is what is done for earth dams...a mixture of 
different size particles to prevent water from moving through freely.  As 
long as the granules are the same shape, the pore space will remain the 
same.  Hope this helps...
