The Best Blackberry Crisp

Mid-September, the apple trees at their best. The Macintoshes are fully ripe — I've been picking and eating them every day, the small tart apples that are the best pie apple I know and one of the better eating apples when you want something that bites back. I pressed cider at the Hendersons' this weekend, the annual ritual, twelve gallons. Two glasses standing in the barn while it was still warm from the press. That taste: September in Vermont, specific and unrepeatable.

The fall foliage is beginning to build. The early maples on the ridge are going fast — more color this week than last, the hillside across the valley shifting from green to mixed. In ten days it will be the full display. I've been watching it from the kitchen window in the mornings, which is a good way to watch it: unannounced, while doing other things, letting it come to you.

Teddy and I started the stocks curriculum. Veal stock was Sunday: the roasted bones, the mirepoix, the long simmer, the clarification. A full day of work for what amounts to a few quarts of liquid that changes everything it touches. He listened to the explanation of the gelatin extraction as if it was the most interesting thing he'd heard all week. It might have been. He said: so the bones are doing the work. I said: the bones are doing the work. He said: everything is about what's underneath, isn't it. I said: in cooking, yes. He said: everywhere, I think. I said: yes. Everywhere, I think.

The stock was done by evening — bones strained, liquid gold in the pot — and Teddy had gone home with the kind of quiet that follows a real lesson. What I wanted after all of that was something simple, something that asked nothing of me except to trust the fruit. We still had blackberries from the last August picking, frozen and waiting, and a crisp is honest work: you let what’s underneath do the talking, just like the bones. This is the one I come back to every fall.

Prep Time: 15 min | Cook Time: 45 min | Total Time: 1 hr | Servings: 8

Ingredients

For the filling:
6 cups fresh or frozen blackberries
1/4 cup granulated sugar
2 tablespoons cornstarch
1 tablespoon fresh lemon juice
1 teaspoon lemon zest
For the crisp topping:
1 cup old-fashioned rolled oats
3/4 cup all-purpose flour
3/4 cup packed light brown sugar
1/2 teaspoon cinnamon
1/4 teaspoon nutmeg
1/4 teaspoon salt
1/2 cup (1 stick) cold unsalted butter, cut into small cubes

Instructions

Preheat. Heat oven to 375°F. Lightly butter a 9x13-inch baking dish.
Prepare the filling. In a large bowl, toss the blackberries with the granulated sugar, cornstarch, lemon juice, and lemon zest until evenly coated. Pour into the prepared baking dish and spread in an even layer.
Make the topping. In a separate bowl, combine the oats, flour, brown sugar, cinnamon, nutmeg, and salt. Add the cold butter cubes and work them in with your fingertips until the mixture resembles coarse, clumpy crumbs with some pea-sized pieces of butter remaining. Do not overwork.
Assemble. Scatter the topping evenly over the blackberry filling, covering it completely.
Bake. Bake for 40—45 minutes, until the topping is deep golden brown and the fruit filling is bubbling around the edges. If the topping browns too quickly, tent loosely with foil for the last 10 minutes.
Rest and serve. Let the crisp rest for at least 10 minutes before serving. Serve warm, with vanilla ice cream or a pour of cold heavy cream if you like.
