Wash strawberries, allow them to dry and then place them in a large mixing bowl.
Crush the strawberries using a potato masher.
Measure out 2 1/2 C of the crushed strawberries and place them in a separate bowl.
Add the chopped pineapple to the strawberries.
Slowly add the sugar and stir until the strawberries, pineapple and sugar are well combined.
Place cold water in a saucepan and place it on the stovetop over medium heat.
Add the pectin and stir continuously until water begins to boil.
Allow the water and pectin mixture to boil for 1 minute, then remove it from the heat.
Pour the water mixture into with the fruit and stir well to combine.
Continue stirring for 4 minutes.
Pour the fruit mixture into pint freezer containers leaving an inch of space at the top, then cover the container.
Let the fruit filled containers stand at room temperature for 24 hours, then place them into the freezer.
The jam will stay good in the freezer for up to 6 months.
To use the strawberry jam, remove it from the freezer and allow it to come to room temperature. This should take about 1 hour.
When you have used the amount of jam you want for that meal, cover the container and refrigerate it. It will keep for up to 3 weeks in the refrigerator.
