This dessert came to be for a few reasons. One: it's the first day of fall and this seems like the perfect bridge-into-autumn dessert, using late summer berries and incorporating Bosc pears from the farmers market. Two: I've been awfully into rustic, free-form desserts lately. Recently, Linnea was up in Sonoma--ambling around the square with her mom--and brought home a book called Rustic Fruit Desserts by Cory Schreiber and Julie Richardson. Both are from Portland, OR and Julie owns a little small-batch bakery there by the name of Baker and Spice. She started out selling her tarts and crumbles at the farmers market...and business grew. I can see why. There's just something nice about unfussy desserts with a reliable crust that showcase beautiful, seasonal fruit. The ingredients are simple: mainly butter, sugar, buttermilk, eggs, and fruit. And the method almost seems intuitive, as if you're keying into something that people have been doing the same way for years and years.
