In a large bowl, whisk together flour, baking soda, baking powder & salt. With a pastry blender or finger tips, cut in white & yellow Crisco shortening. In a measuring cup, place the egg & vinegar then add enough COLD water to make 1 cup; whisk together. Make a well in center of flour & pour ALL liquid in. With hands combine quickly but do NOT over mix. This recipe will should give you enough for about 3 – double crust 10-inch pies. Whatever you don’t use, freeze for later use. This is so handy when time is short & dessert is needed. At this time, roll out a 10-inch bottom pie shell, place in pie pan & refrigerate until ready to fill. Take the same amount of pastry, form it into a ball, wrap in plastic wrap & place it in the freezer. When you are ready for the top pastry on your bumble berry pie, remove the ball from the freezer & GRATE it over the top of the fruit.
