One popular sweet iced tea recipe is to boil 3 cups of water and put in two family-sized tea bags, boil for another minute, then cover and let it steep for 10 minutes. After removing the teabags, dissolve 1/2 cup of sugar in the tea, and add 7 cups of cold water.
In total, completing this recipe should only take 20 minutes. Serve this tea over ice, yielding 2 1/2 quarts of sweet tea. To make peach iced tea, stir in a 33.8 ounce bottle of peach nectar and 1/4 cup of lemon juice to 1 1/2 quarts of the sweet tea, yielding about 2 1/2 quarts. To make tea 'n' lemonade, stir a cup of thawed lemonade concentrate into 2 quarts of the sweet tea, yielding about 2 1/4 quarts. If you are making the sweet tea to be served on its own, you can add up to 1 full cup of sugar during preparation depending on personal preference.
Another, similar recipe for sweet tea calls for adding a pinch of baking soda to the boiling water before the tea bags. More interesting variants include sweetening the tea with honey instead of sugar and adding grated ginger to the drink.
