Oh my, you are going to end up with lots of iced tea recipes. I don't drink sweet iced tea but I do make it for company and my kids as they like it. Here's mine
Boil 2 cups water with a pinch of baking soda in a pan. Disolve in 3/4 cups caster (also called granulated or white) sugar. If using black tea (in the US, Pekoe is the most common for iced tea), add 5* tea bags immediately to the boiled water and steep for about 10 minutes. (If using green tea, don't heat the water to boiling but just under boiling).
Pour mixture in a 2 quart picture. Add an additional 4 cups of cold water. Serve over ice or refrigerate until cold. I won't drink iced tea that has set for more then a day.
*If you are using loose leave tea, add enough to make 5 cups of hot tea.
If it's too sweet, reduce the sugar next time. If too strong, reduce steeping time or reduce down to 4 tea bags.
To me, lemonade is such a personal taste on how tart or sweet you like it and how tart your lemons are, that I'm hesitant to give a recipe. The only advice I have is to make a few cups of sugar water and let it chill, squeeze your lemons, put the lemon juice into a picture and start adding sugar water till you get it to the tartness/sweetness that you like. Here's a link to a basic recipe.
