In a large bowl, mash fresh raspberries. You want some larger pieces, but majority should be mashed. This will yield just over 3 cups.
Add sugar to the mashed raspberries and let it stand at room temperature for 5-7 minutes. Stir at the midway point of resting.
In a small sauce pan, whisk together the water and pectin. Bring to a boil and stir the entire time. Boil for 45 seconds.
Pour the pectin water over the berries. Stir gently for 2 minutes.
Spoon the jam into clear jars. Make sure to leave about ½-3/4 of an inch of space at the top.
Seal the jar with the lid. Allow the jam to cool on the counter and set for at least 6 hours. Transfer to the freezer and store up to 12 months. The jam will keep in the fridge for about 2-3 weeks.
