I make this recipe with cold brew tea bags, but if you want to make the tea the way you prefer first, that is fine too. You just need 2 quarts of prepared tea.
Prepare cold brew tea by steeping two tea bags in 2 quarts room temperature water with 1 cup of the sugar for 5 to 10 minutes, or until the strength of tea is to your liking.
While tea is steeping, place the 5 chopped strawberries with the remaining water and sugar in a sauce pan over medium heat. Let come to a simmer and simmer for 10 minutes. Strain strawberry liquid through a fine mesh colander gently crushing the berries to get the juice out of them. Let liquid cool and add in lemon juice.
Add strawberry/lemon mix to the steeped tea, discarding the tea bags. Mix to combine everything together.
Taking an ice cube tray, place sliced of the 3 strawberries into each container. Carefully, pour the tea mixture over the strawberries and place in freezer to freeze. Place remaining tea in a pitcher and let get cold in the fridge.
When tea is cold and ice cubes are frozen, pop out the ice cubes, add to a glass with lemon slices (optional) and pour in the tea. Serve and enjoy!
