Crush berries to desired consistency - do not strain (see note).
Mix with lemon juice.
Gradually whisk in pectin.
Set two timers simultaneously - one for 30 minutes and one for 5 minutes. Mix every 5 minutes for 30 minutes. This ensures that the pectin is completely mixed in.
After the 30 minutes, whisk in sugar.
Whisk for 2-3 minutes until the sugar is completely dissolved.
Transfer to CLEAN jars.
Let set for 24 hours.
Freeze or refrigerate after jam as set for 24 hours.
Notes
The amount of berries you use can vary slightly, within a half of a cup. More variation than that will lead to problems with your jam setting up.Fruit (and vegetables) naturally contain pectin, and different kinds of fruit contain differing amounts of pectin. Softer fruit has less pectin, more firm fruit has more pectin. They way freezer jam sets up is through adding more pectin. The most common reason for freezer jam to not set up is a problem with the pectin to fruit ratio. Doing things like straining the pectin can vary this ratio.
