Fill your water bath canner with water, place on stove and warm on medium-high heat while you follow steps below
Measure out your sugar and set this aside
Put 7-8 cups of fresh strawberries into a food processor and pulse them until they are pureed, make sure to leave some chunks in it
Measure out exactly 5 cups of pureed strawberries into a stock pot
Put the stock pot with the strawberries on the stove over high heat
Add the sure-jell packet
Bring to a strong boil (meaning that it continues to boil even when you stir it), make sure you constantly stir the mixture during this process
Add in the sugar and mix it in
Bring mixture to a full boil, stirring occasionally
Once at a full rolling boil set timer for 1 minute
When timer goes off remove from heat and skim off foam with a spoon
Remove hot jars from oven or dishwasher
Pour jam mixture into jars with a funnel, being cautious not to overfill (I usually try to leave at least a 1/4th inch at the top)
Clean off the tops of the jars to ensure a good seal and place clean, new lid along with lid ring on jar
Put jars into water bath canner, water should be softly boiling, and your jars should be completely covered with water when lowered into pot
Boil for 20 minutes
Remove from canner and set on counter to let jars seal and cool
Notes
This recipe makes 4 pints
You can easily double the recipe, but it takes a large pot to cook it all together so we prefer to make multiple single batches
Your jam may be liquidy when you pour it into the jars, it will set within 24 hours after canning it
If you want less sugar buy no sugar needed pectin, however don’t reduce the amount if you use regular pectin or the jam won’t set correctly
It is best eaten within a year, but the sugar acts as a preservative and it will be safe to eat even after that year is up if you forget about it. Once the jar is opened, keep in the refrigerator and use within a few months.
