Blackberry Lavender Jam
From Ball Fresh Preserver, Food in Jars
Makes 6 half pint jars
Ingredients:
- 3 pounds blackberries (about 6 cups
crushed)
 - 2 ½ cups granulated sugar
 - 2 tablespoons Ball Classic
Flex Pectin
 - 2 teaspoons freshly squeezed lemon
juice
 - 1 tablespoon lavender
 
Instructions:
- Prepare a boiling water bath and 6
half pint jars.
 - Place the blackberries in a large
pot and cover them with fresh, cool water. Agitate the berries gently to help
release any leaves or twigs. Drain and repeat. 
 - Using a potato masher, crush the
berries into a chunky pulp. Whisk the sugar and pectin together and add to the
fruit. Stir to combine.
 - Tuck the lavender into a tea
strainer or tie it up in a length of cheesecloth and add it to the pan. Let the
lavender infuse into the berries for at least an hour.
 - When you’re ready to cook, place
the pot on the stove over high heat and bring the berry pulp to a boil, stirring occasionally.
 - Reduce the heat to medium-high and
cook the fruit for 8-10 minutes, stirring constantly to prevent scorching, until the jam sheets off your spoon and passes
a set test. Stir in the lemon juice.
 - Remove the pot from the heat and
ladle the jam into the prepared jars. Wipe the rim, apply the lid and band, and
process in a boiling water bath for 10 minutes. Repeat and complete this step for
each jar to avoid assembly line filling.
