1.) If you plan on using frozen berries, allow them to thaw completely and drain any extra juices from them before mixing with the remaining ingredients.2.) Use enough berries so that they form a small mound in your pie plate. Berries will sink when baked so it's better to use more than not enough. Each pie plate has a different depth and diameter. Fill it with enough berries accordingly.3.) Whole cane sugar can be substituted with white sugar. 4.) Whole Wheat Flour can easily be substituted with all purpose flour, spelt flour, or your favorite gluten-free flour mix.
