The tart crust was made from the sweet tart dough recipe in the same book. That dough includes an egg, an egg yolk, and baking powder in addition to the butter, flour, and sugar. It was mixed in a food processor and then wrapped in plastic and left to rest in the refrigerator for 20 minutes or so. It was more dough than I needed for my rectangular tart pan, so I also made a small, free-form rustic tart to leave at home. The filling was made with frozen blueberries, sugar, a tablespoon more of cornstarch than the four tablespoon suggested, and nutmeg. After cooking and thickening, cold butter was stirred into the blueberry filling mixture. The ample crumb topping was made by combining flour, baking powder, cinnamon, brown sugar, and melted butter. Once folded together, it was left to sit while prepping the tart shell and filling. Often it’s tempting to double the quantity of a crumb topping, but I can tell you this recipe made plenty and doubling it would have been way too much. Once the filling was spooned into the shell and the crumble topping was sprinkled on top, the assembled tart baked for 40 minutes.
The crust was flaky and golden and lovely, and the filling was just firm enough and full of blueberry goodness, but the crumble topping was my favorite part. Those nuggets of buttery, crunchy, fun were a delight on top of the tart. It could have been almost any fruit in the filling because in the end, the blueness of it didn’t matter at all, but I’m glad that concept led me to this tart anyway.
