Round these parts, the summer fruit scene has been a little crazy. Notoriously fickle peaches have been consistently juicy and flavorful, while my stand-by, blueberries, have been tiny and sour and hardly fit for a pie. Blackberries, which I had long given up on in protest of paying $4.99 for a pint of purple pebbles, have been the summer all-stars. I've been buying pint after pint of the gorgeous, giant blue-black berries. Even the local ones have measured in at an inch long or more.

I recently turned a few quarts of berries into jam. And what lovely jam they made: intensely plummy with large chunks of fruit and some errant, crunchy seeds. I love how the sturdiness of blackberries make them perfect for preserve-style jam—even after cooking, they don't break down completely.

This jam makes the perfect topping for fruit bars, which are essentially an extra thick shortbread cookie topped with toasted almonds and preserves. The special trick to these is the whipped, sweetened egg white mixture that is dolloped on top before baking. The toasted meringue-like layer adds sweetness and helps secure the jam to the bars.

Each bite is a mix of buttery crumb, toasted almonds, and sweet blackberries. I think they're awesome picnic bars, though I've been known to eat them for breakfast, too. Don't feel pressured to make your own jam—any quality preserve will do. Just look for something with visible chunks of fruit.

Ingredients

For the Crust:

  • 2 cups (10 ounces) all-purpose flour

  • 1 cup confectioners sugar

  • 16 tablespoons cold unsalted butter

  • 2 tablespoons milk

For the Topping:

  • 1/2 cup confectioners sugar

  • 1 egg white

  • 1/2 teaspoon almond extract

  • 1 cup blackberry jam

  • 1/3 cup slivered almonds, toasted

Directions

  1. Make Crust: In the bowl of a food processor, pulse together flour and confectioners sugar until combined. Add butter and pulse until butter is the size of peas. Add milk and pulse until dough comes together into a ball. Press dough evenly into prepared pan and place in refrigerator for 30 minutes.

  2. Adjust oven rack to middle position and preheat oven to 350°F (175°C). Grease baking dish with butter. Place almond slivers on a baking sheet and toast until golden, 6 to 7 minutes.

  3. Bake crust until just beginning to color on top and brown on edges, about 20 minutes.

  4. Make Topping: In a medium bowl, whisk together egg whites until frothy, then whisk in confectioners sugar until smooth. Whisk in almond extract.

  5. Spread jam evenly over top of parbaked crust. Dollop egg white mixture over top, leaving sporadic patches of jam peeking through. Top with toasted almonds. Bake until topping is golden, about 15 minutes. Let cool, then cut into 12 bars and serve. Store cooled bars in a sealed container at room temperature for up to 5 days.

Special Equipment

9- by 9-inch baking pan, rimmed baking sheet, aluminum foil, food processor, whisk

Notes

I like to use slightly chunky jam—and homemade is best. If needed, swap in raspberry or blueberry for blackberry.
