coarsely chopped rhubarb
Bring 6 tablespoons of sugar and 1/4 cup of water to a boil in a saucepan, stirring just until sugar dissolves; remove from heat. Cool.
Place 1 1/2 lbs Coarsely chopped Rhubarb in a wide mouth jar. Add 3 cups Vodka, 1/2 cup Grand Marnier, or other orange flavored liquor, and cooled sugar syrup; stir.
Screw lid on tightly; let stand at room temperature for 2 to 3 weeks or until all the color leaches out of the Rhubarb. Strain mixture through a sieve over a bowl; discard solids.
