1 lb rhubarb, washed and cut in 1/4" slices
1 1/4 cups sugar
1 3/4 cups water
optional: a few slices fresh ginger, a slice of star anise, a splash of rosewater or orange flower water
Toss the rhubarb, sugar and water in a pot, stir, and bring to a boil. If you're using any optional herbs or spices, add them now. Lower the heat until it's just enough to maintain a simmer. Cook until the rhubarb breaks down entirely, ~20 minutes. Pour through a strainer, giving the rhubarb goo a stir to allow all the syrup to drip through. Stir in the orange flower water or rosewater, if desired. Cool, and add to the beverage of your choosing.
