1. Combine first 5 ingredients and 1 cup water in a medium saucepan over high heat. Bring to a boil, reduce heat to low, and simmer 5 minutes or until sugar dissolves. Remove from heat, strain through a wire-mesh strainer, and set aside.
2. Place 1 cup strained liquid in refrigerator to cool. When cool, sprinkle gelatin over liquid; stir and let stand one minute. Add gelatin mixture to remaining liquid and whisk until blended and dissolved, about 5 minutes.
3. Transfer mixture to a storage container, and chill until jelly is set, 4 hours or overnight.
