Rhubarb Crisp Squares: A Taste of Spring

The first time I tasted rhubarb crisp, it was at a church potluck in late spring. The air was thick with the scent of lilacs and freshly cut grass, and the table groaned under the weight of homemade pies, salads, and casseroles. But it was the unassuming dish of rhubarb crisp that stole the show. The tart, bright rhubarb, softened and sweetened, nestled under a golden, buttery crumble, was a revelation. Each bite was a perfect balance of sweet and tangy, a reminder that even the humblest ingredients, when treated with care, can create something truly special.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 35-40 minutes
• Total Time: 55-60 minutes
• Yields: 16 squares
• Dietary Type: Vegetarian

Ingredients

For the Filling:

• 4 cups chopped rhubarb, thawed if frozen
• 1 cup sugar
• 2 tablespoons cornstarch
• 1 teaspoon grated orange zest

For the Base/Topping:

• 1 1/2 cups all-purpose flour
• 1/2 cup packed brown sugar
• 1/2 cup chopped pecans
• 1 teaspoon ground cinnamon
• 1/4 teaspoon salt
• 1/2 cup butter or 1/2 cup margarine, softened

Equipment Needed

• 8-inch square baking pan
• Medium saucepan
• Mixing bowl
• Pastry blender or two knives (optional, for cutting in butter)
• Measuring cups and spoons
• Oven
• Cooling rack

Instructions

1. Begin by preheating your oven to 350°F (175°C). This will ensure even baking and a perfectly golden crust.
2. Next, grease an 8-inch square cake pan thoroughly. This prevents the squares from sticking and makes for easy removal later. Use butter, shortening, or a baking spray to achieve a non-stick surface.
3. Prepare the rhubarb filling. In a medium saucepan, combine 4 cups of chopped rhubarb (thawed if frozen), 1 cup of sugar, 2 tablespoons of cornstarch, and 1 teaspoon of grated orange zest. The cornstarch will help thicken the filling as it cooks, while the orange zest adds a bright, citrusy note that complements the tartness of the rhubarb.
4. Cook the filling over medium heat, stirring constantly. This is crucial to prevent sticking and ensure the sugar dissolves evenly. Continue cooking for approximately 5 minutes, or until the mixture has thickened and the rhubarb has softened slightly.
5. Remove the saucepan from the heat and set the rhubarb filling aside to cool. This allows the flavors to meld and prevents the filling from becoming too runny during baking.
6. While the filling cools, prepare the base/topping. In a mixing bowl, combine 1 1/2 cups of all-purpose flour, 1/2 cup of packed brown sugar, 1/2 cup of chopped pecans, 1 teaspoon of ground cinnamon, and 1/4 teaspoon of salt. The pecans add a delightful crunch and nutty flavor, while the cinnamon lends warmth and spice to the crust.
7. Cut in 1/2 cup of softened butter (or margarine) using a pastry blender, two knives, or your fingers. Work the butter into the dry ingredients until the mixture resembles coarse crumbs. The goal is to create small clumps of butter coated in flour, which will create a tender and flaky crust.
8. Set aside 1 cup of the flour mixture to be used as the topping. This reserved mixture will create the crumbly topping that gives the dessert its signature texture.
9. Press the remaining flour mixture evenly into the greased cake pan. This forms the base of the crisp, providing a sturdy foundation for the rhubarb filling. Ensure the base is compact and even for consistent baking.
10. Spread the cooled rhubarb filling evenly over the pressed base. Distribute the filling to all corners of the pan to ensure a uniform layer of rhubarb goodness.
11. Sprinkle the reserved flour mixture evenly over the top of the rhubarb filling. This creates the crumbly topping that bakes into a golden-brown crust. Gently distribute the mixture for even coverage.
12. Bake in the preheated oven for 35 to 40 minutes, or until the topping is golden brown and the filling is bubbling. Keep a close eye on the crisp during the last few minutes of baking to prevent the topping from burning. A toothpick inserted into the center should come out with moist crumbs.
13. Remove the pan from the oven and place it on a cooling rack to cool completely. Allow the crisp to cool completely before cutting into squares, as this will allow the filling to set and prevent it from being too runny.
14. Once cooled, cut into squares and serve.

Expert Tips & Tricks

• For an extra layer of flavor, try adding a splash of vanilla extract or almond extract to the rhubarb filling.
• If you don’t have pecans on hand, you can substitute other nuts, such as walnuts or almonds.
• If you find that the squares are a little watery, place them in the refrigerator. They should firm up nicely.
• To prevent the topping from burning, you can tent the crisp with foil during the last 10-15 minutes of baking.
• For a richer flavor, use browned butter in the base/topping. Simply melt the butter in a saucepan over medium heat and cook until it turns golden brown and smells nutty. Be careful not to burn it.

Serving & Storage Suggestions

Serve the rhubarb crisp squares warm or at room temperature. They are delicious on their own or with a scoop of vanilla ice cream, a dollop of whipped cream, or a drizzle of custard.

Leftover rhubarb crisp squares can be stored in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. To reheat, simply warm in the oven at 350°F (175°C) for 10-15 minutes, or until heated through. You can also reheat individual squares in the microwave.

For longer storage, you can freeze the rhubarb crisp squares. Wrap them individually in plastic wrap and then place them in a freezer-safe container. They can be frozen for up to 3 months. Thaw overnight in the refrigerator before reheating.

FAQs (Frequently Asked Questions)

Q: Can I use frozen rhubarb?
A: Yes, you can use frozen rhubarb. Be sure to thaw it completely and drain any excess liquid before using it in the recipe.

Q: Can I make this crisp ahead of time?
A: Yes, you can assemble the crisp ahead of time and store it in the refrigerator for up to 24 hours before baking. You may need to add a few extra minutes to the baking time.

Q: What if my topping is browning too quickly?
A: If the topping is browning too quickly, you can tent the crisp with foil during the last 10-15 minutes of baking.

Q: Can I use a different size pan?
A: Using a different size pan will affect the baking time. If using a larger pan, the crisp will bake faster. If using a smaller pan, it will take longer.

Q: How do I know when the crisp is done?
