Look for dried hibiscus blossoms (jamaica) in Latino markets. Or use Celestial Seasonings' hibiscus-flavor Red Zinger tea as directed on package to make 3 quarts. If making ahead, cover and chill tea up to 2 days.
1 cup (1 1/2 oz.) dried hibiscus blossoms
1 cinnamon stick (about 1 in.)
About 1/3 cup sugar
How to Make It
In a 4- to 5-quart pan on high heat, bring 3 quarts water to boiling. Add hibiscus blossoms and cinnamon stick. Cover and simmer over low heat for 15 minutes. Let cool about 1 hour.
Pour tea through a strainer, lined with a double thickness of cheesecloth, into a pitcher. Discard residue in strainer. Pour tea, hot or cold, into ice-filled glasses. Add sugar to taste.
