Sweet, no lemon. If a restaurant only has un, then I'll get it and add Splenda. Hubby won't get iced tea at a restaurant if it's unsweetened. Sugar won't disolve in cold tea, unless you add tons, at which point it looks like you're drinking a snow globe.
We have a huge mint bed and we used to make mint syrup to add to our tea. Eventually I found myself putting less and less tea in the glass and drinking only the mint syrup. Hubby called me a hummingbird for a while. I had to give it up totally when I realized it was the cause of my added weight.
I admit it, I like the Luzianne liquid concentrate that we use at Lions Club functions when we have to make many, many multiple gallons at a time. As for the powdered stuff, GROSS!
