Iced tea simply is tea cooled and served with ice, but it can also simply mean tea that was cooled. One can add sugar or syrup to sweeten, or leave it without extras. This drink became really famous in many forms, especially with various fruit tastes.
The pronunciation of “iced tea” has final sound of “d” almost as “t” what commonly happens in modern English with double consonants.
Iced Tea: What It Is and How to Make It
The World Exhibition of 1904 in Saint Louis marked a decisive moment for iced tea. Imagine twenty millions of visitors here during extremely warm summer, all very thirsty. Here iced tea saved the situation, and after folks tried it, the popularity only grew from then.
Making iced tea at home does not require special talent. With tea packets you can have it ready in only five minutes. Basic method includes black tea, a bit of sugar and juice of lemon.
The secret that none mentions is brewing the tea more strognly than usually. Because later you will thin it with cold water and ice, that strength will stop it from tasting slim or watery. Consider it as creation of a strong base.
Follow the directions on the package: if it says three to five minutes, stay at five.
After dipping, remove the tea packets. Want it sweeter? Mix in sugar until it fully dissolves.
Pour everything in a jug, add cold water and leave it rest in the refrigerator at least one hour. Serve it over ice when you are ready to drink, that is the essence of the name. A slice of lemon is useful, and it forms the traditional style.
You maybe heard about the old method of sun tea. One lays a jug of water with tea packets or leaves outside in the sun whole day, while it naturally steeps. The problem is that sun tea can help bacterial growth, which does matter a lot.
A more reliable way is cold brewing directly in the refrigerator. For iced tea of that kind never use warm water… It simply steeps slowly in cold water on its own time.
The advantage of the fridge weigh is its easy scaling. Prepare ten servings works just as well as one cup. Put the right amount of tea in a jug with water and leave it stand simply.
Black tea with lemon forms the reliable pair. Assam gives robust, malty taste that projects against ice and mixes well with sweetener, ideal for sweet iced tea. Ceylon tea gives more vivid, citrus flavor with pure finish, making it light and fresh.
White and fruit teas work well in iced form. Puree from mangoes adds well to sweet tea, they naturally sweeten and give the drink a bit denser texture. Most people find that one cup of puree for two cups of tea reaches the right proportion.
Iced tea has some downsides. It provides caffeine together with real refreshment. Tea stores many antioxidants, and green tea is linked to lower cancer risk according to studies.
One annoying spot is cloudiness, especially if your water is rich in minerals. Add a pinch of baking soda beforeblending to prevent the reaction between tannins and caffeine that causes that cloudiness.
