I love to drink homemade iced tea in the summer. Here is how I do it:
Fill a large cooking pot with 2 liters (quarts) of water and add 1 cup of sugar. Bring to a rolling boil (it will take a while). Turn the heat off and add 6 to 8 bags of black, fruit or herbal tea and let steep for 10 to 15 minutes. Remove the teabags and mix the tea with cold water in the ratio of 1 part of tea to 3 parts of water. It is important to cool the tea down quickly as this preserves the flavour.
You can add ice cubes, slices of lemon or mint leaves. My family likes lemon and summerberry tea best, but black tea is also delicious especially with lemon.
