Another recipe I have used to preserve the blueberries was simply blueberry jam. It is very easy! I did change the recipe up a little and used less sugar.
- Take 9 cups of crushed (and washed) blueberries and 6 cups of sugar and mix together. I only use about 4 cups of sugar. (You can use a potato masher to crush your blueberries while it heats.)
- Heat until all the sugar dissolves and the mixture starts to gel.
- Using your funnel pour the jam into your jars.
- Place lids on.
- Process in a hot water bath for approximately 10 minutes.
