This recipe is simple, and delicious hot or cold. You can use fresh or frozen blackberries. We eat it cold in summer, warm in winter. I have used fresh and frozen berries and have seen no difference in the finished product. Since I try to reduce gluten, I use Einkorn flour in it. Same amount called for, no adjustments necessary.
Hoping you love this as much as we do!!
