This recipe is the sister recipe to my other blueberry syrup recipe. THAT recipe is not able to be canned due to the corn starch in it. THIS recipe IS because there is no cornstarch and a few tweaks to the instructions. Both syrups are delicious but this recipe is adapted for canning instructions.

📝 Frequently asked questions, answers and tips:
For this recipe, you are welcome to use fresh or frozen blueberries. There is no need to thaw the frozen blueberries if you are using the frozen berries. Want to freeze your own blueberries? I show you how to freeze blueberries and how to make a delicious blueberry jam recipe for all you blueberry lovers.
I use a pinch of salt in this recipe because a touch of salt compliments and brings out the sweetness of fruits such as blueberries. You are welcome to leave it out but I encourage you to give salt a try.
It is not recommended to use cornstarch as a thickener in recipes when that recipe is going to be canned at home. The starch continues to thicken as it cools and is not safe for water bath canning. Cornstarch can be used as a thickener in pie fillings but the pie filling should be used right away or frozen instead of canned. Be sure to try my corn starch free sour cherry pie filling!

This is delicious! We only got 2 and 1/2 half pints but flavor is amazing. The syrup is thick and yummy. We used double strength vanilla at the same measurement and will definitely make this again. Thank you.
Jenn
This is a great recipe! The final measurements are definitely off though. I doubled the recipe and got 4 1/2 pints. So expect to only get 2 1/2 pints if you follow the recipe. Very yummy though!
Nancy
I thought the final volume of 4 (1/2 pint jars) from 2 cups of berries and 1/3 cup water didn't add up and I was correct. Those proportions only yield 2 (1/2 pint jars).
As mush as my family loves vanilla, (I usually add more than called for), we felt it overpowered the blueberries. Next time I will add less.
Otherwise, this was very good, immersion blending gave it a nice consistency.
First time I canned since helping my mother back in the early 60's. Much better in air conditioning and not a hot kitchen in the country.
Sarah Mock
I would add an additional 5 minutes to the processing time for pint jars.
Diane
Would this turn out just as good if I double the receipt and put in PINT jars, and process for a bit longer?
Sarah Mock
Tricia,
Let me see if I can help.
step 3: cook for 2 minutes
step 4: blend (immersion blender or food processor, be careful either way)
step 5: add vanilla if using,
step 6: prepare the water bath.
I am wondering if in step 2 I should make a note to put on a pot of water for the water bath. I am trying to save you time by starting the water bath when you start the blueberries to boil.
I hope that clears it up.
Sarah
Tricia
I’m confused. You boil for two minutes then pour boiling mixture into blender then return to the stove? I feel like I’m misunderstanding step 3 to step 6.
Sarah
Ann,
I am so glad you love this recipe! If you have more frozen blueberries be sure to make my lemon blueberry bread or blueberry jam. And if you have fresh blueberries I HIGHLY recommend Blueberry salsa.
Ann M. Carlson
Just made this with frozen berries and it is DELICIOUS. Super easy! Thank you so much.
Sarah
Mary Ann. I would be comfortable with doubling this but not tripling it. Others may disagree with me I am comfortable with doubling it. Do what you feel is right for you.
Mary Ann
Is it a problem to double the recipe? (I know for some canning recipes they suggest not to so wanted to check!) thanks :)
Sarah
Great catch Debra!!!It going in with the water in step 1. I have adjusted the recipe!
Debra Blodgett
There is mention of using 1 Tbls Lemon Juice but it isn't in the instructions. Do you add to the blueberry mixture or do you add it in the jar at the end
Sarah
