4 cups water, 1 cup sugar
Heat one cup of water to boiling (I microwave in a Pyrex measuring cup) and then add the tea bags to the water. Let the tea steep for at least 5 minutes, then remove the bags and let the liquid tea cool down a little.
2 black tea bags, 4 cups water
Add the frozen juice concentrates, sugar water, brandy, and tea to a 2-quart freezer-safe container. Stir to evenly mix and ensure the frozen juices have fully thawed and distributed.
6 ounces frozen orange juice concentrate, 6 ounces frozen lemonade concentrate, 1 cup brandy
Cover and freeze overnight.
When ready to serve, scoop into serving glasses (fill about half full) and then top with lemon-lime soda.
