Blueberry Maple Preserves

Blueberry Maple PreservesEdit – August 2017: I have omitted adding water to the blueberry preserves I made this year because I now prefer a much thicker preserve that is more like a runny jam. I have adjusted the recipe accordingly but you can certainly still add some water if you prefer a more runny syrup. I found that I ended up with one less jar than when I added water. I also now use 1/2 pint (500 ml) jars because we were wasting quite a bit because we didn’t use a whole pint of preserves quickly enough once a jar was opened. 

Fall has started early this year here in Ontario and part of me is enjoying the cooler temperatures. I also find it depressing because of looming thoughts of winter and the reality of climate change. The farmers will be having a tough time this fall so I’m doing my bit to support the local farmers in my area as much as I can.

Even though I get maple syrup straight from the farmer, it is still expensive. I buy the darkest maple syrup I can find because I love the flavour. When at the farmers’ market, I have to go to the Mennonites that don’t have flashy stalls to get the really dark syrup. I suppose that it isn’t as popular as the other grades but I don’t know why. You get plenty of sweetness and it is packed with maple flavour. I strongly recommend getting the darkest maple syrup you can for this recipe. To cut down on the cost of this canning project, I mix the maple syrup with a simple sugar syrup. By using such a dark grade of maple syrup, I am able to maintain a strong maple flavour in the finished product even with the simple syrup.

My initial goal was to make preserved blueberries using the cold-pack method. I did make a couple of batches this way but I am still working out how to not get the syrup to piss all over the counter after I remove the jars from the canning pot.

If you aren’t familiar with what cold-pack canning is, it is when you put raw fruit in the jar and then cover it in hot syrup. The time in the water-bath is much longer than if you put hot preserves or jam in. Juice and sometimes air within the fruit is naturally released from the fruit during the canning process and this has been a real pain in my ass. I will work on de-bubbling the jars better and I hope to have the recipe perfected by next summer. I will post it then. For now, I am sharing my recipe for hot-pack canning blueberries. You lose some of the texture of the blueberries, but the fruit doesn’t float as much and you get a nice dark preserve that is more syrupy.

It is about time that I share with you all some other news. It is a little appropriate that I share this news on a post where the dominant colour is blue since we found out back in June that we are having another little boy. If you remember back in the spring when I announced the baby news, I did so on my Cinnamon Bun post.

We have a name picked out but you won’t find that out until the baby is born. We have to keep some element of surprise to ourselves. Follow me on Twitter and Instagram if you want to catch the news and photos of the new little dude that will arrive mid-November. If this new little boy is half as cute as my Timothy, you are in for a treat. I’m not biased or anything though. I also promise not to live-tweet the labour, cuz that’s just gross.

Ingredients

  • 10 cups fresh blueberries
  • 1 cups water (optional)
  • 2 cups dark maple syrup
  • 1 cup granulated sugar
  • 1/4 cup bottled lemon juice

Instructions

  1. Fill a large canning pot with hot water and place a rack on the bottom. Bring it to the boil. Wash five* 1 litre (pint) canning jars with new lids. Make sure the rings are in good shape, ie. no rust or dents. Add a splash of plain vinegar to the canning pot to prevent hard water marks on the jars.
  2. Put the clean jars in the canning pot and boil for 10 minutes to sterilize the jars. Turn the heat off and leave the jars in the water to keep hot.
  3. Put the lids in a small pot with water and bring to the boil about 5 minutes before you will be using them. Let it simmer for a few minutes and then turn the heat off, also keeping the lids warm so that the rubber edge remains soft.
  4. Add all the ingredients to a large heavy-bottomed pot and bring it all to a rolling boil. Stir often to prevent scorching and skim off any foam that develops.
  5. Boil for approximately 15 minutes for a thin syrup. Boil for longer for a thick syrup or a more of a runny jam consistency. You can put some on a cold plate to see how runny it is. Keep in mind that it will thicken slightly as it cools. If you choose to omit the water it will take less time to get to the desired consistency but it does effect your yield as does how long you boil it for. Less time means there is more liquid which means a slightly higher yield.
  6. Remove the jars from the hot-water bath and place them on a board covered with paper towel. Fill the jars with the hot preserves using a funnel. Leave 1/2" (1 cm) headspace. Use a chopstick or dull plastic knife to dislodge any bubbles that may be trapped amongst the preserves.
  7. As you fill the jars, bring the canning pot back to the boil.
  8. Wipe the rims with a clean, damp cloth and place the warm lids on the jars. Put the rings on and tighten the rings just until you meet resistance (aka 'finger-tight).
  9. Place the jars in the canning pot, put the lid on the pot and bring it to the boil. Once the water is boiling, put the timer on for 15 minutes.
  10. When the timer goes off after 15 minutes of processing time, turn off the stove and remove the lid from the canning pot. Let the jars sit in the water for 5 minutes before removing them and placing them on a board with a tea towel or paper towel.
  11. Let the jars sit undisturbed on the counter for 24 hours and then check to see if the lids have all sealed. Enjoy any jars of preserves that do not seal within a couple weeks and store those in the fridge. The jars that seal are good for up to a year and store them in a cool, dark place.
  12. You will yield 4.5 litres of preserved blueberries (less if you omit the water). More if you boil the preserves for less time before adding them to the jars.
Recipe Type: Preserves

Notes

*You can prepare some 500ml (half pint) jars instead of all litre jars. If you end up with a less than full jar, just use that jar first as the excess air in the jar will decrease its shelf life.

Edit: I reduced the amount of water in the recipe from 2 cups to 1 cup to cut down on the cooking time so that you get thicker syrup much more quickly.

    Holy geez, this sounds amazing! I can totally picture spooning it over pancakes or waffles! So excited you're having another little boy!

    Best tasting blueberry preserves ever! These taste like they were made on a pioneer wood stove. The Maple syrup taste comes through and it takes me back in time to mom's farm kitchen. Pure nostalgia. I put some with Cottage Cheese and also had some on cottage cheese pancakes. And some I ate right from the jar. Next up will be some Frozen Yogurt with Blueberry preserves.

      Sorry, but I'm not selling it online. If you aren't interested in canning such a large amount, you could reduce the recipe down considerably to make enough for about one jar and keep it in your fridge for up to a week. I haven't done it myself but perhaps, 1 1/2 cups blueberries, 1/4 maple syrup, 2 tbsp sugar, tbsp water, 2 tsp of lemon juice -- boiling in a pot and then transfer it to a jar. That should get you something comparable to what I make.

    I just made my third annual batch of these preserves, and it's all I can do not to eat the hot blueberry syrup straight out of the pan. (Though I'm resisting the urge. Because I like my tastebuds and have no interest in burning them into oblivion.) Thanks again for sharing this recipe. It's become something of a tradition for us. I always get a little teary eyed when I crack open the last jar of the previous year's batch.
