Do you ever go to a new restaurant, wonder about the quality of their iced tea, try it, then regret your decision?
Nearly twenty years ago, I developed a hypothesis: I noticed that the restaurants that offered captain's wafer crackers, rather than the run of the mill (square) saltine crackers had a better tasting iced tea.
I don't have the hard numeric data to quantify the study, but I will tell you that almost without fail, the hypothesis stands. Therefore, I declare the Captain's Wafer Theory.
Let me know if you find the same results.
