Can fresh berry pie filling made w/cornstarch be frozen?
I taught a pie class the other day, and I am up to my neck in pie. I find myself with a batch of fresh blueberry filling (the kind that goes into a fully-baked pie shell, not the kind that still needs to be baked), which was thickened with cornstarch. I actually made it 3 days ago. I'm wondering if this can be successfully frozen, then thawed later to make a pie when all the other pies around here are gone. Thanks.
