Break out the mini umbrellas for this exotic, rum-optional elixir. For a lighter drink, you can make a spritzer with 2 Tbs. of the hibiscus syrup and 3/4 cup seltzer water. Serve with a straw for stirring.
1. Steep tea bags in 1 1/2 cups boiling water 15 minutes. Strain, and discard tea bags; transfer liquid to saucepan. Stir in sugar, and return liquid to a boil. Reduce heat to medium-low, and boil 15 minutes, or until liquid is reduced by half. Transfer to bowl, and place in freezer 10 minutes, or until mixture is syrupy. 2. Fill glasses with ice. Pour 2/3 cup pineapple juice and 1 oz. rum (if using) into each glass. Add 1 1/2 Tbs. coconut milk, and drizzle 2 Tbs. hibiscus syrup over coconut milk. Garnish with pineapple slices and mint sprigs.
