Christina's Rhubarb Crisp

from marthastewart.com

• 12 tablespoons chilled (1 1/2 sticks) unsalted butter, cut into small pieces, plus more for ramekins or baking dish
• 1 cup plus 1 1/2 tablespoons all-purpose flour
• 1/2 cup packed dark-brown sugar
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon grated nutmeg
• 1/4 teaspoon salt
• 1/2 cup old-fashioned rolled oats
• 2 pounds (6 large stalks) rhubarb, cut into 1/2-inch pieces (6 cups)
• 1 teaspoon grated orange zest
• Juice of 1 orange
• 1 vanilla bean, split and scraped (or 1 tsp vanilla extract)
• 1/2 cup granulated sugar
• 2 tablespoons cornstarch

Preheat oven to 350 degrees. Butter six 8-ounce ramekins (or a 2 1/2-quart shallow casserole), and set aside. Make crumb mixture: In a large bowl, whisk together flour, brown sugar, cinnamon, nutmeg, salt, and oats. Using a pastry cutter or two knives, cut in chilled butter until mixture comes together into clumps, about 4 to 5 minutes; set aside.

In a large bowl, stir to combine rhubarb, zest, orange juice, and vanilla seeds. In a small bowl, combine sugar and cornstarch; sprinkle over rhubarb until just coated. Pour 1 cup rhubarb mixture into each ramekin, and top with 1/2 cup crumb mixture. Bake until the rhubarb is tender when pierced with the tip of a knife, about 30 minutes (or about 45 minutes for the casserole). Transfer from oven to a cooling rack. Let cool slightly, and serve warm with vanilla ice cream.

Christina's Rhubarb Shortbread

For the Jam

1 pound rhubarb, trimmed and cut into 1-inch pieces
1/2 cup granulated sugar
1/2 cup water
1 vanilla bean

For the Shortbread

4 cups all-purpose flour
2 teaspoons baking powder
1/4 teaspoon salt
1 pound (4 sticks) unsalted butter, room temperature
4 large egg yolks
2 cups granulated sugar
Confectioners' sugar, for dusting

Make the jam: Combine rhubarb, sugar, and 1/2 cup water in a medium saucepan. Split vanilla bean, scrape the seeds into the pan, and toss in the pod. Bring to a simmer over low heat, cook, stirring often, until rhubarb softens and forms a soft mass, about 10 minutes. Remove and discard vanilla bean. Transfer to a shallow bowl and let cool. Can be made ahead and refrigerated in an airtight container, for up to one week. If refrigerated, return to room temperature before using. You may substitute 1 cup of your favorite jam or preserves for the homemade.

Make the shortbread: In a medium bowl, whisk together flour, baking powder, and salt. In the bowl of an electric mixer fitted with the paddle attachment, beat butter on high speed until pale and fluffy. Add egg yolks and sugar, and beat until sugar is dissolved and the mixture is light. Reduce mixer speed to low, and add the dry ingredients, mixing only until the ingredients are incorporated.

Turn the dough out onto a work surface and cut into two pieces. Shape each piece into a ball and wrap in plastic wrap. Place in freezer until firm, about 30 minutes. Can be made ahead and frozen for up to one month. Thaw in refrigerator overnight.

Assemble and bake: Preheat oven to 350 degrees with rack in center. Remove one ball of dough from freezer and, using the large holes on a box grater, grate the dough into a 9-by-13-inch baking dish. Pat the dough gently just to get it into the corners (you don't want to press it down), and spread with the rhubarb jam. Grate the remaining dough over the jam, and press it lightly to distribute it evenly. Bake until golden brown, about 40 minutes. Dust with confectioners' sugar as soon as it is removed from oven. Cool on a wire rack.

Cut the shortbread into bars when it is cool. You can cut whatever size bars please you, although as a rough guide, 3-inch squares, or rectangles 1 1/2 inches by 3 inches make nice servings. Store covered at room temperature for up to 2 days.
