How to Make Cherry Rhubarb Jam
Step 1: Prep the Rhubarb
Wash and dice fresh rhubarb into small pieces.
If using frozen, thaw and drain any excess liquid before starting.
Step 2: Cook the Rhubarb and Sugar
Combine the rhubarb and sugar in a large saucepan.
Cook over medium heat, stirring frequently, until the sugar dissolves and the rhubarb softens—this should take about 15–20 minutes.
Step 3: Add the Pineapple
Stir in the crushed pineapple, including the juice.
Cook for another 3 minutes to let the flavors blend.
Step 4: Add the Gelatin
Remove the pan from heat and stir in the cherry-flavored gelatin until completely dissolved.
Step 5: Fill the Jars
Carefully ladle the hot jam into sterilized jars, leaving about ¼ inch of headspace at the top of each jar.
Step 6: Seal and Process
Wipe the rims clean, secure with lids and bands, and process the jars in a boiling water bath for 10 minutes to ensure a safe seal.
Step 7: Cool and Store
Remove jars from the water bath and place them on a towel.
Let them cool completely.
Once cooled, check that the seals are tight, then store in a cool, dark place.
