Rhubarb ginger jam Recipe

Chop rhubarb into 1/2 inch chunks. (The fresher the rhubarb, the better the taste of the jam. Try for a 15 minute maximum.)
Place in large stock pot with 1/4 cup water and cook until rhubarb is soft.
Add ginger and pectin; cook over high heat, stirring constantly until mixture reaches a full rolling boil (cannot be stirred down).
Add sugar all at once, and bring back to a full rolling boil.
Cook, stirring constantly, for 2 full minutes.
Remove from heat and add food color.
Place in steamed jars with new lids, invert for 5 minutes.
