Bring juice to a boil in a medium sized sauce pan over high heat.
Once boiling, add pectin and stir quickly for 1 minute.
Turn off heat and add lemon juice and sugar. Mix well.
Return to a hard boil and stir for ~3 minutes or until the syrup becomes thick.
Remove from heat and skim off any foam that formed while boiling.
Once done, carefully fill a mason jar (I used a wide mouth funnel) and allow to cool. I let my jelly set up overnight.
Cover and refrigerate (lasts around 2 weeks).
If keeping in pantry:
Boil enough water to cover your mason jar and lid. This will sterilize it. When jam is ready to be removed from heat, carefully remove mason jar and lid.
Carefully pour jam into the mason jar (I used a wide mouth funnel).
Place lid on and turn over the jar. Leave upside down for 10 minutes.
This will seal the jam and allow you to store it in the pantry/counter/etc. I let my jelly set up overnight.
Refrigerate after opening. Enjoy!
Notes
*I triple this recipe when I make it. I also use smaller jars in order to get a more reasonable size when using.**If you don’t plan on eating the jam immediately, this is for storing in the pantry.
