The easiest strawberry jam recipe I've ever made.
Prepare the strawberries by hulling and cutting up into pieces. Put strawberries and lemon juice into a pot. Turn on medium-high heat. Allow them to heat up. As the strawberries heat, I use my spoon to mash them as they get soft.
Mix 1 cup sugar with the box of pectin. Once the strawberries are boiling, mix in the sugar and pectin. Stir well. Add the rest of the sugar to the mixture.
Bring to a boil. It should be a rolling boil that doesn't slow down if you are stirring. Allow to boil (as you stir) for one minute. Remove from heat.
Ladle the jam into prepared jars waiting for you. Use a water bath canner and process the jars for 10 minutes. Let the jars sit for 24 hours before removing rims and labeling the cans!
