In a large pot, combine the dried hibiscus flowers and water.
Bring the water to a boil over medium-high heat. Once boiling reduce the heat to low and let the hibiscus flowers simmers for about 10 minutes. Remove the pot from the heat and let the hibiscus tea steep for an additional 30 minutes to 1 hour.
The longer it steeps, the stronger the flavor will be..
After steeping, strain the hibiscus tea through a fine mesh sieve or cheesecloth into a pitcher to remove the flowers.
Stir in the sugar until dissolved. Adjust the sweetness to your liking by adding more sugar if desired.
If using, stir in the pineapple juice for added flavor.
Chill the hibiscus ice tea in the refrigerator until cold or serve immediately over ice.
Garnish with fresh mint leaves and slices of lemon or lime if desired.
