Back in 1928, the cookbook "Southern Cooking" published an excellent recipe for sweet tea. It then became an icon in Southern cuisine. Alcohol was a common addition until Prohibition. That part of history is over, so you can add Southern Comfort to your tea if you want. I have my own opinion about why Southerners love their tea sweet. Everywhere I've gone that is tropical or enjoys hot weather, people love sweets. Where it is colder, most people tend to go for unsweetened tea. That's my story, and I'm stickin' to it.
