Blueberry Pie Filling to Can, Sugar-free

Blueberries….are one of the easiest berries to take care of. When we purchased this property there were 6 blueberry bushes along the woods. I do have to compete with the birds some years especially when it is dry. My blueberry bushes provide me with gallons of fruit with very minimal care. There isn’t any peeling or pitting, just pick the berries and eat them!!!

Blue berries have a lot of health benefits. They contain a plant compound called anthocyanin which gives them their blue color and many health benefits. They are all high in Vitamin C.

I have used Clear Jel for many years to thicken pie fillings. This product is not on-plan per Trim Healthy Momma but I do use it as it is a type of resistant starch. Thermflo appears to be the best in resistant starch in this kind of thickeners. These thickeners are a type of waxy maize heat modified starch with is used for some medical conditions to keep their blood sugars stable for hours.

This is how thick the filling will get after you cook it with the Clear Jel in it. I added a few blueberries before I remembered to take a picture. Below you will see how the filling looks after all the blueberries are added.

Blueberry Pie Filling will get thinner after it has been canned. If you want it a little thicker for a pie so the pieces hold their shape better, add 2 teaspoons unflavored gelatin to a quart of filling when you make a pie. That works wonders.

This pie was made with Sourdough Pie Crust and canned Blueberry Filling. It was so delicious! This is one of the reasons I like to keep canned pie filling on hand…..it makes a quick dessert. This pie plate is an old aluminum one from my grandma. I love using it for something special!
