Lower-Carb Blueberry Pie

 I've posted before about using almond flour for pie crust to lower the carb content of a pie.  I haven't done this for fruit pies previously, mostly because fruit pies typically have some sort of top crust.  I decided to give it a try with a topless blueberry pie.

I used my go-to recipe for the almond flour pie crust:

1 1/2 c almond flour

2 tbsp Whey Low D

1/4 tsp salt

1/4 c almond oil (or butter, or coconut oil)

I mixed this up and pressed it into the pie plate:

The filling ingredients I got from a recipe online somewhere, but don't have the link:

1 1/4 c Whey Low D (as a lower-carb replacement for sugar)

1/3 c clear jel (as a low-carb replacement for flour)

1/4 tsp salt

1/2 tsp cinnamon

5 c blueberries

The powdered ingredients are substantial:

 

In the shell, ready to go in the oven:

 

 As usually seems to happen, the crust got a little over-done, at least in appearance (after about 40 minutes at 425).

I don't have any pictures of what happened when it was cut open, but I have not had much success in getting blueberry pie filling to  hold together.  It tends to fall apart when cut, and that held true this time, as well.  Still, it was no worse than normal.  This was my first attempt with clear jel, and I thought that might be the solution (as well as lowering the carb count).  However, it didn't work out as hoped.  The crust's flavor was fine, even though it was dark.

The blueberries themselves have a lot of carbs, of course (about 18 net grams per cup, accoring to Fat Secret).  Assuming the Whey Low D has about 20% of the carb hit of regular sugar (see discussion here), the carb load for the entire pie would be about 300 grams, or 38 grams per slice.  That isn't exactly great; it's a pretty solid hit for someone who has carb issues.  However, it compares very favorably to a pie made with wheat flour and sugar, which would be around 150 grams per slice (increasing to about 168 grams if a top crust is added).  Relatively speaking, it's not bad--though a nut-based pie would be much lower.

It's something potentially useful to keep as an option for lower-carb baking.
