The Jelling PointAs the juice-sugar mixture nears the jelling point, test frequently. Dip a spoon into the boiling jelly. Remove and allow the juice to drip from the side of the spoon. As the jelling point nears it will drip from a tipped spoon in two drops ¼ to ½ inch apart. When the jelling point is reached the two drops will run together and drop off in one sheet. A candy thermometer may be used instead of the jelly test to determine the proper jelly stage. At sea level the temperature should reach 200 to 222 degrees F. At higher altitudes it is reached at a slightly lower temperature. For each 960 feet above sea level, lower the temperature by 1.8 degrees. |
Preparing the Jars and Sealing the Jelly
Many older recipes call for sealing the jelly with paraffin. This method is no longer recommended, as spoilage is possible and not as harmless as once thought. Current methods call for the jelly to be sealed and processed in a boiling water bath. The processing time depends on the size of the jar and the altitude.
Clean and inspect the jars carefully for nicks or cracks. The rim of the jar must be nick free or the jar will not seal. Jars and rings may be reused, but you should use new lids each time. Place the clean jars into a large kettle or canner. Cover with water and bring to a boil. Boil for 10 minutes, then maintain a simmer until ready to add the jelly. Process the lids according to the manufacturers instructions.
When the jelly is ready, remove the jars from the water bath and drain quickly, Do not worry about drying. Skim the jelly and pour into the jars quickly, filling to within ¼ inch of the rim. (Leave a ¼ inch head space.) The use of a canning funnel helps prevent spills. Wipe the jar rim with a damp towel to remove any jelly that may have landed on it and prevent sealing. Put the lid and ring on the jar and hand tighten. Put the filled and sealed jars back into the boiling water for the recommended time. Remove and set on the counter to cool. When the jars are cool, test the seals to be sure they sealed. Any jar that did not seal should be put into the refrigerator for immediate use.
Jelly That Did Not Jell
If the jelly does not jell, you have several options. First, you could call it syrup and pretend it is perfect. But, if jelly is your desire you have several options.
For fruits high in pectin, you can remake the jelly by adding 2 tablespoons bottled lemon juice to each quart of jelly. Clean and re-sterilize the jars. Heat jelly and lemon juice to the boiling point and boil again, testing for the jelling point as previously described. Fill the sterile jars and seal again with new lids. Repeat the sealing process as described.
You can also remake using commercial pectin. Clean and re-sterilize the jars. For each quart of jelly, add ¼ cup sugar, ½ cup water, 2 tablespoons bottled lemon juice and 4 teaspoons powdered pectin. Bring to a rolling boil over high heat, stirring constantly. Boil hard 1 minute. Remove from heat, quickly skim foam off jelly and fill clean sterile jars, leaving ¼-inch headspace. Adjust new lids and process again as recommended.
