(For those that didn't spend part of their childhood on a tobacco farm, I don't know how else to describe it. For those who did, I sympathize with your memories of leaf rash and staking in sweltering heat of August.)
Nothing like being under 14 without a worker permit, hungover, on the back of a wagon, smoking a Marlboro, some guy shouting at you, having wet tobacco leaves slapping you in the face every time you lean over to puke, and then grabbing that bottom leaf that has the big fat juicy worm on it at 7 am.
Growing up in rural Eastern NC was just the cat's meow. At age 14 I wised up retired from priming tobacco and got a job shoveling .... and silage on a dairy farm, lol
But I digress ...
Personally I have fair amount of the good old TA still around but rather than search or bother with the intricacies of finding an actual replacement for an existing product that I realistically know nothing about the composition of with another similarly named but different product that I realistically know nothing about the composition of, I am going for Option C:
Reformulating recipes that I used TA in with FlavourArt Seven Leaves instead ( also a product that I realistically know nothing about the composition of, but am already familiar with, lol).
