Remove the large green leaves, if they are still attached, and wash the stalk thoroughly.
Chop the rhubarb into pieces. Try and get the pieces to be less than one inch wide.
Add the rhubarb to a pot.
Add 1 cup of water and ⅓ cup of sugar.
Bring the mixture to a boil over medium high heat and then drop the heat back to medium.
Simmer for 15 minutes.
Stir occasionally because the bottom tends to want to scorch.
Once the rhubarb is cooked down, strain it through a fine mesh strainer.The finer your strainer the more clear the syrup will become.
Pour the rhubarb syrup into a glass jar and store it in the refrigerator
Use within 2 weeks.
