Hello Mentors,

I have finally made a profile on here though I have been using this forum as a reference guide for years.I have recently started attempting to run and create some "rheumatism medicine" through a turnip still.While I have read alot on this site I often find myself miffed by some of the terminology. If possible I would like some advice on how to better the quality of my output.So heres what I have been up to.
My Mash: 30 lbs cornmeal,30 lbs sugar,40 gallons purified water.1 jar of fleischman highly active yeast
I put cornmeal in my 55 gallon barrel,all of it.I add 20 gallons of water and stir with wooden paddle till cornmeal absorbs the water and starts to congeal.
Next I add my sugar,then the rest of the water, again I stir as to blend ingredients and dissolve sugar,I pitch my yeast maybe 5 tablespoons or so.I mix again this time bottom to top to ensure everything is mixed.I cover barrel with bedsheet,tie of with a rope and leave alone.I let it work for 7 days it bubbles and pops like the dickens.
I run 10 gallons of mash at a time through my stil(as that is all it holds at once)l.when Im done I end up with about 5 gallons of "rheumatism" medicine.Now this is where my problem comes in.
The shine I am collecting has a slightly odd odor.without cuts or blending.from the head through the hearts to the tails has the dreaded wet cardboard odor I have read about multiple times on this forum.The stuff is strong.Will get you drunk as a skunk.but the odor is my main concern.Also when I run it.It is clear but with a slightly white hugh barely visible but you can notice it isnt crystal clear.and to my last concern I have the pleasure of being from eastern tennessee and had the pleasure of enjoying some of popcorns finest.In his you could taste the sweetness of the corn even through the over bearing rocket fuel moonshine flavor.I know this man was a legend and cAnnot expect to duplicate such a spectacular product with such a piss poor mash recipe but I wanna get close.I have read tried and true upside down and saw the u.j.s.m. as well as others,when popcorn ran his still he was cooking his mash almost whole corn kernels floating in it and all,which on this site was said to be bad because of scorching ....however seems like all the big guys do it espicially when using submarine pots.it is fermented and cooked within the same vessel.I just want someone who has ran a ton of it,to tell me how to improve recipe,get rid of bad smell,and improve clarity as well as output.Again I apologize for the long post,and I thank you for your time,
