Jam Crumb Bars
These bars provide the perfect contrast of crisp and gooey. For a chocolate variation, omit the jam and evenly scatter fourteen ounces of finely chopped semisweet chocolate over the cooled crust before proceeding.

Ingredients
Preparation
Step 1
Preheat the oven to 350°F. Butter a 15-by-10-inch rimmed baking sheet. Line with parchment paper, leaving a 1-inch overhang on the long sides. Set aside.
Step 2
In a large bowl, whisk together ground almonds, flour, sugar, and salt. Cut in the butter with a pastry blender until the mixture resembles coarse crumbs. Using your fingers, squeeze the mixture together to create pea-size crumbs with a few larger clumps.
Step 3
Transfer half of crumb mixture (about 4 1/2 cups) to prepared baking sheet; set aside remaining mixture. Cover with a sheet of parchment paper. Using the back of a large spoon, press dough evenly into pan, lifting the parchment occasionally to ensure it doesn’t stick. With a wine bottle or small rolling pin, roll along the length of the pan to smooth dough. Dough should be firmly packed, with no holes or cracks. Bake, rotating the pan halfway through, until lightly golden all over, 15 to 20 minutes. Transfer pan to a wire rack to cool completely.
Step 4
Evenly spread jam over cooled crust. Scatter with remaining crumb mixture, squeezing some of the mixture so that large clumps are visible and evenly distributed over the top of the jam. Bake, rotating the pan halfway through, until the topping begins to turn light golden brown (the jam should not be too dark), 20 to 22 minutes. Transfer pan to a wire rack to cool completely.
Step 5
Run a knife around the edges of the pan to loosen; using two wide spatulas, transfer to a cutting board and cut into 3-by-2-inch bars. Bars can be kept in an airtight container at room temperature for up to 4 days.

Step 6
