Using a knife, peel them from the films. Just need to lift a little, and they easily come off in strips.
300 g rhubarb

Pour into the pot where you will cook the jam, add granulated sugar.
300 g sugar

Put on the stove, boil after boiling for 5 minutes. There is usually almost no foam on this jam. Turn off the heat, cover with a lid and let stand for 2 hours. The stalks will absorb the aromatic syrup as they cool.
Then repeat the procedure, boiling for 5 minutes after boiling. The jam will become thicker.
