Prepare the hibiscus base. In a medium saucepan, bring 4 cups of water to a boil. Remove from heat, add the dried hibiscus flowers or tea bags, and let steep for 10 minutes until the liquid turns a deep ruby red.
Strain the tea through a fine-mesh strainer into a heat-resistant pitcher, pressing gently on the flowers to extract all the flavor. Discard the used flowers or tea bags.
Add sweetener while still warm. Stir in the honey or maple syrup while the tea is still hot, ensuring it dissolves completely. Taste and adjust sweetness if needed.
Prepare the strawberry infusion. In a small bowl, mash half of the sliced strawberries with a fork until they release their juices. Add the mashed strawberries, remaining sliced strawberries, and mint leaves to the hibiscus tea.
Add the remaining ingredients. Stir in the lemon juice and remaining 2 cups of cold water. Mix well to combine all flavors.
Chill thoroughly. Refrigerate for at least 2 hours or overnight to allow flavors to meld and develop. The longer it sits, the more pronounced the strawberry flavor will become.
Strain again if desired. For a smoother tea, strain out the fruit pieces before serving, or leave them in for a more rustic presentation.
Serve with style. Pour over ice in tall glasses, garnish with fresh strawberry slices, lemon wheels, and mint sprigs for an Instagram-worthy presentation.
