I happened to have some extra pie dough in the fridge. Half was rolled out into a pan in the freezer and half was still in a disc. There were several kinds of berries in the fridge but not enough of any one to make a pie, so I combined them all (about 5 cups worth) with 3/4 cup sugar, 1/8 teaspoon fine sea salt, 1/2 teaspoons ground cinnamon, 2 tablespoons of cornstarch and 4 teaspoons of tapioca starch. (When Alex monopolizes the scales I have to make do with imperial measurements.) It was very hot and humid in the kitchen that afternoon so instead of attempting to roll out the second crust I crumbled it into streusel and spread it over the top of the berries. Then I scattered raw sugar over the streusel and baked the pie at 400°F. for 20 minutes, reduced the heat to 350°F, and baked it for another 45 minutes.
Pie dough streusel might just be my new favorite thing.
