Insubstantiation?

So last Summer I exchanged a pie (read Ashley's review in the comments of that post) for a Wolfgang Puck deep fryer and a mandolin (not the musical kind).

Since the pie was not for me, I didn't get to taste it, so I was greatly anticipating Concord grape season to roll around again, so I could taste it this time. And the last go-round through the produce aisle, there were some Niabell grapes from CA that advertised themselves as "Concord-like."

I've taken to calling this my communion pie, because of Ashley's comments, and because an unleavened crust with a grape is very Adventist communion palate. I find it best not to get too carried away with this comparison because sacrilege and blasphemy are a slippery slope. I'm now going to take the comparison too far and be sacrilegious and blasphemous.

My understanding of the Roman Catholic sacrament is that there's transubstantiation where the wafer and wine become the body and blood of the Christ. Does transubstantiation work both ways? If I truly pour my soul into making this pie, does my blood and body become the pie components? Or does reverse Transubstantiation require a different term, like Insubstantiation--from soul to substance. And with making the crust Wednesday night, seeding the grapes Thursday night (about 90 minutes of work for 2 pounds of grapes), the pie will rise on the Third Morning; Remind you of anyone?
