Pour contents into a large saucepan. Simmer over medium heat until it comes to a boil.
Reduce heat and simmer for a total of 10 minutes, stirring frequently. Pour hot sauce into 2 pint size mason jars (or airtight containers) and fasten lids.
Let jars cool until they reach room temperature, then use immediately or refrigerate for up to 2 weeks.
Notes
The best way to store homemade blueberry barbecue sauce is in an airtight container or mason jar in your fridge. This will keep it fresh and tasty for up to two weeks.
If you have lots of sauce, it’s also safe to freeze it for later. Be sure to let it cool before adding to an airtight container. It will keep in the freezer for up to 3 months.
