Okay, friends. Before we go any further, you might want to pop on over to read this link. Marisa is the canning guru, and she’ll tell you everything you need to know about hot water canning, which is the method I reference in the first line of this recipe for my Blueberry Pie Filling (“set up a hot water bath”).
So, the next thing I should mention is this is the first season I’m making pie filling to store for the long haul. I know, I gasped a little bit at the idea of that, too. Usually I just fill the freezer with more berries than seemingly possible, and work my way through them. This whole year of pie endeavor is what inspired me to finally can filling for long term storage. That, and the fact that I have a wonky freezer, and live in an area susceptible to power outages.
The freezer is an easy fix, right? Just buy a new one. Except, I’ve been wanting to do a DIY kitchen renovation, and it’s a much better idea to buy new appliances when (or if?) that project gets going. Speaking of which, have any of you tackled demo’ing cabinets, and putting down new flooring? I’d love to hear your stories or advice.
Back to the Blueberry Pie Filling, though. It’s incredible easy to make, and if you don’t want to take on a canning project, go ahead and cook the filling, then add to your favorite crust (um, there are a lot of recipes for crust here). The filling is enough to make two to four pies, depending on if you want smaller ones, or standard 9-inch pies.
A word about the cornstarch. I know it seems like a LOT of starch. Feel free to adjust based on how runny you prefer you fruit pies (read: use less cornstarch for a soppy filling). I’m guessing some of you might ask how long to bake it for, yes? Honestly, I don’t have the answer just yet since I usually bake with fresh fruit. I’ll recommended 15 minutes at 425ºF first, because that always helps set the tone for a nice golden crust. Turn it down to 350ºF after that initial bake, and start checking around 30 minutes. The tell tale sign of a done pie is filling gurgling out of the vents on the crust (or lattice if you go that route). Happy pie making!
Blueberry Pie Filling
- 2 quarts little less than 1.5 kilos fresh blueberries, picked over for stems & leaves
- 2 cups 400 grams granulated natural cane sugar
- 7 to 8 tablespoons 56 to 64 grams cornstarch
- ¼ cup fresh lemon juice from about 2 large, juicy lemons
- 4 sterilized glass pint jars rings & lids
- Set up a hot water bath.
- Add the berries, sugar, cornstarch, and lemon juice to a deep pot over medium-high heat. Stir until the berries release some juices. Bring to a boil, then reduce heat to low. Simmer, stirring frequently, until juices thicken, and sugar and cornstarch dissolve completely.
- Spoon the filling into the jars. Add them to the hot water bath, and process for 35 to 40 minutes. Let jars cool completely before storing
