Classic Blueberry Pie
Why This Recipe Works
For many years we have tried using flour and cornstarch to thicken fresh fruit pies, but the results have been uniformly poor. After testing cornstarch, flour, tapioca, and arrowroot, we found that the samples of fruit thickened with the root starches, arrowroot and tapioca, were clear and bright in appearance and had the clearest fruit flavor. Of the two, tapioca showed a bit more thickening power and was therefore our favorite. So we developed a fruit pie recipe employing this favorite.
