When you spend 12-hour days working on the newspaper, sometimes you get a little batty. That might explain our behavior at the Standard on Thursday night when a blind taste test suddenly erupted.It all started, the best I can tell, when someone mentioned spaghetti sauce and whether Ragu tasted better than a generic store brand. Before you know it, I was at the vending machine buying Coke and RC Cola and pouring them in cups to see if anyone could tell the difference.Despite everyone assuring me with great confidence they could easily tell the difference between the two, that wasn’t the case once the sampling began as it ended up being an even 2-2 split.The shaky results had our newsroom testers wanting to try more samples with publisher Pat Zechman suggesting I go out and buy pizza from Domino’s, Pizza Hut, Papa John’s and Little Caesars to see if they could tell the difference.
