This can be used to flavor soda water (or probably some cocktails.) It's a tart/sweet taste, a bit like cranberries. It can be used as a substitute for Grenadine syrup. Ingredients 1/3 c. (90 ml) Dried hibiscus petals ( these can be obtained from vendors of herbal tea) 1/2 c.(125 ml) Sugar or honey 1 c. (250 ml.) Water Directions Put all 3 ingredients in a saucepan & stir, while bringing to a boil. Once it boils, reduce heat to a simmer. Stir intermittently for 15 minutes. Allow to cool for 45 minutes to an hour. This will allow it to condense & thicken a bit more. Strain leaves out and transfer to a larger container. Once leaves are strained, pour the liquid into a jar. A mason jar or airtight bottle work well. Refrigerate. This should be good for 2-3 weeks. I like to add 2 tablespoons (30 ml.) to 1 liter of soda water. I hope I got the metric measurements right. Apologies if I am a bit off.
