The process and ingredients of making fruit pie fillings, particularly this easy homemade blueberry pie filling is somewhat similar to making blueberry jam. The only difference, I would say is the use of cornstarch in the pie filling and pectin in the jam.
I have written quite a bit about pectin in jams in my homemade strawberry jam post here, so basically, an alternative to pectin would be lemon juice. And since I also use lemon juice in my blueberry pie filling, practically the only difference between the pie filling and the jam is the use of cornstarch in the former and none in the latter.
Pectin, Lemon Juice and Cornstarch – When to Use
Pectin and lemon juice act as the gelling agents in the jams which is how jams are supposed to be. But that does not mean that the jams are thick, they are still a bit runny, but more of a gel consistency. Cornstarch, on the other hand, thickens the mixture which is ideal for pie fillings. Too runny a filling will turn your pies soggy, so thicker fillings are most suited for pies.
Anyhow, even though I said lemon juice is not required for pie fillings as the gel like consistency is not required, you will notice in my recipe below that I still added some lemon juice to my blueberry pie filling. This is because the lemon juice and the lemon rind simply enhances the taste of the blueberry pie filling. So, just in case you are little confused with my explanation about the role of lemon juice in helping jams to set, the only reason I add it to my pie filling is because of the taste and nothing else.
How to Make Blueberry Pie Filling – Video Tutorial
Check out my video on how I made this blueberry pie filling:
- White sugar
- Lemon juice
- Lemon zest
Making the homemade blueberry pie filling
- The process typically starts by getting the blueberries ready. Once the fruits are all weighed, washed and drained, add half of them into a saucepan placed over very low heat.
- And then add in the sugar. Also add in the lemon juice, lemon rind and cornstarch. To avoid the cornstarch turning lumpy, it is best mixed with some water first before being added into the blueberries. As the sugar starts to dissolve, you will notice that the fruits mixture turns quite runny and the blueberries start to soften. At this stage, add in the salt and then the remaining blueberries.
- Let the mixture simmer over low heat while stirring it every now and then until it thickens. The pie filling is ready when the liquid in the mixture has reduced to the point that the fruits are just coated in the sugar sauce.
- At this point, remove the pie filling from the heat and let it cool completely to room temperature before storing it.
Storing the homemade blueberry pie filling
- Since I always make a fresh batch whenever I need to use the filling, storing has never been an issue for me. I always just store it in a clean container in the refrigerator.
- But if you intend to keep the filling for more than a week or so, I would suggest storing them in heated jars. Simply warm your clean jars in the oven and spoon the cooled pie filling into the warmed jars and close the lids. Keep the filling refrigerated until it is ready to be used.
