Blueberry Lemon Crunch Bars

Consider yourself warned: A crunch may look like a bar cookie, but you’ll need a fork to eat it. Similar to a crisp with baked fruit and a crumbly topping, a crunch sandwiches a layer of jammy fruit between two buttery layers. While other fruit desserts are on the syrupy side, this fruit is cooked down into a flavor-packed, thick preserve. The bottom layer should be firm enough not to crumble when a piece is cut from the pan, so adding toasted pecans to the mix improves the taste as well as the texture. The top layer can duplicate the bottom, or it can be a simple streusel topping made with flour, sugar, and butter.
