Sweet tea indicates the need for sugar and lots of it. When Southerners travel up north, they often order "tea" with their
meals and get unsweet tea without ice. When we order tea,no matter where we are, we expect sugar and lots of it poured over lots of ice. "Sweet iced tea" is the way you'll often hear us describe it. "Would you like a glass of sweet iced tea?" Or ... we may just say, "Tea?" You should know what that means ...
For the record, "sweet iced-tea" is always best served on a hot day and in Mason jar ...
"Sweet milk" means you don't want buttermilk. Personally, I never took to buttermilk, but my mother swore it was "so gooood" especially when served with some hot apple pie.
