Wash, hull and crush strawberries in a LARGE (10 to 14-cup) microwaveable bowl to equal 4 cups. You may use a potato masher, food chopper, or food processor to crush the strawberries; do not puree--leave slightly chunky. Add lemon juice and Pectin. Mix well. Let it sit at room temperature for 20 minutes.

Add sugar; stir until mostly dissolved. Heat in the microwave on high for 10 minutes until boiling and foamy. (Keep an eye on it so it doesn't boil over.) Remove and stir one last time. Mixture will still be thin.

Skim the foam off the top, then pour jam into clean freezer containers leaving ½-inch head space for expansion. Your jam should look consistently chunky throughout the jar after it is poured into the jars. If the fruit has risen to the top and the liquid remains at the bottom, pour the fruit back into the bowl, add one additional Tablespoon of Pectin and heat again until boiling and foamy.

Immediately top with lids and let stand at room temperature for 1 to 2 hours to cool down before placing in the freezer.
