Okay, "desperate times call for desperate measures!" Have you
ever been BBQ'ing a steak or pork chop and had the edge curl up
because of the fat/grizzle on the outside of the meat? What do you
do? You cut the through the fat so the meat will then lay flat!
I would first get the okay from your pathologist/investigator, but I'm
thinking if you place a cut strategically on the surface of the block,
when the section hits the water, it will be able to "relax" and lay flat
for you. I should also warn, this advice is as yet untried. But I refer
you back to the cliche in line one. Good luck. (And definitely tell me
if it works)
