Sterilize the Mason jar by washing it thoroughly with soap and hot water, then boiling it for 10 minutes.
Fill the jar with the homemade jelly, leaving about 1/4 inch of headspace at the top of the jar.
Wipe the rim of the jar clean and screw the lid on tightly.
Label the jar with the date the jelly was made and store it in the refrigerator.
When ready to use, simply open the jar and serve with clean utensils and enjoy your delicious homemade jelly.
Note: Always use a clean utensil every time you go to get a serving of jelly to help avoid contamination. Store the jelly in the refrigerator and consume within 6 to 12 months for best quality and taste. If the jelly has any signs of spoilage, such as a sour odor or mold growth, discard it immediately.
