Rhubarb jelly is a smooth fruit spread prepared by simmering rhubarb, extracting its juice, and cooking it with sugar and lemon juice until it forms a clear, soft gel.
2 pounds rhubarb, chopped
4 cups water
3 cups granulated sugar
2 tablespoons lemon juice
1 cinnamon stick (optional)
Strain gently for clear texture. Adjust lemon for firmer set. Store in sealed jars after cooling.
