Tips to Making the Best Peach Jam Ever:
Get everything in place before you begin, because there are points in the process where you won’t be able to stop and get what you need.
Don’t be tempted to increase the spice amounts; you want the peach flavor to shine through.
Use the amounts below, follow the directions, and your jam will come out perfect every time. Overcooking and using the wrong proportion of ingredients are the main causes of runny jam.
cups pitted, peeled* peaches, cut in a 1-inch dice
A large bowl of ice water
Zest of half a lemon
Tablespoons fresh-squeezed lemon juice
Tablespoons classic fruit pectin (like Ball® or Pomona’s)
cups white sugar
Tablespoon finely chopped crystallized ginger
teaspoon freshly ground nutmeg
teaspoon ground cinnamon
teaspoon ground cloves
Large canning pot with rack
Jar lifter (typically found in canning sets)
Large tongs (typically found in canning sets)
A wet paper towel
Dry paper towels
one-pint (16 oz.) glass canning jars, with lids and screw-on bands
Peeling Peach Skin
Get your boiling water going in your canning pot. The water should be two inches over the height of the jars. Heat jars, lids and bands in simmering (not boiling) water until ready to use. Remove with tongs and set on dry paper towels. *You can use the same pot to peel your peaches. Cut an X in the bottom of each peach. Drop 4 or 5 at a time into the simmering water for 45 seconds. Immediate remove peaches and drop in a large bowl of ice water for 20-30 seconds. You should easily be able to slip the skin right off the peaches. Repeat this step if the skin is stubborn. In a 6- to 8-quart saucepan, set to medium-high heat, bring the peaches and lemon juice to a boil. Lightly mash the peaches (this will help thicken the jam). Add the pectin and quickly return the mixture to a boil. Stirring constantly, gradually add the sugar. All at once, stir in the crystallized ginger, nutmeg, cinnamon, cloves, reserved lemon zest and salt, and continue to boil, stirring constantly, for 1 minute. Remove from heat. Skim any foam off the top. Ladle hot jam into hot jars, leaving ¼-inch headspace. Wipe rim with wet paper towel. Center lid on jar. Screw on the band until firmly in place. Process in the boiling water bath 10 minutes. Remove jars and cool. Check lids after 24 hours; they should not flex when center is pressed. Label and date your jars. Peach jam will keep up to two years.
