Raspberry Jam

Raspberry Jam
To sterilize the jars and lid rings, boil them in water. The lids should only be simmered, not boiled, so as not to damage the adhesive.
Prep Time: 45 minutes
Cook Time: 25 minutes
Servings: 36 Makes nine 1-pint jars.


  • 12 pints raspberries
  • 14 cups sugar
  • 1/4 cup fresh lemon juice
  • 1 Tbs. lemon zest


Wash the jars and lid rings in a dishwasher or by hand in hot soapy water. Place the jars and lid rings in a large pot of water. Bring to a boil over medium heat and boil for at least 30 minutes. Meanwhile, wash the lids by hand in hot soapy water and place in a small pot of water. Bring to a simmer over medium-low heat and simmer for at least 15 minutes.

Place the raspberries in a large bowl and, using a potato masher, crush them until no pieces remain. Alternatively, crush them in a food processor.

In a large pot, stir together the raspberries, sugar, lemon juice and zest. Place over medium heat and bring to a boil. Cook, stirring constantly, until the sugar dissolves. Increase the heat to high and cook, stirring constantly, until the mixture becomes a thick gel, 20 to 25 minutes. To test the consistency, drop a few drops from a spoon onto a plate. Remove the pot from the heat.

Using tongs or a jar lifter, remove a jar from the water and place on a clean work surface. Ladle jam into the jar to within 1/2 inch of the top. Using a clean, damp towel, wipe the rim clean. Using tongs, remove a lid from the water and place on the jar. Using tongs, remove a lid ring from the water and screw onto the jar until just tightened; do not overtighten. Repeat with the remaining jam and jars. Let the jars stand upright for 10 minutes, then invert them for 1 hour.

Turn the jars upright and check for a good seal; the seal indicator should be depressed. If the seal is not good, invert those jars for 1 hour more and check again. Store all jars in the refrigerator for 1 to 2 months.
