Step‑by‑Step Instructions for Rhubarb Fluff Recipe
Step 1: Prepare the Base
Start by preheating your oven to 350°F (175°C). In a mixing bowl, combine all-purpose flour, margarine, and granulated sugar. Use a pastry cutter or your fingers to blend until the mixture resembles coarse crumbs. Press this crumbly dough evenly into a greased 9×13-inch pan, creating a solid base for the Rhubarb Fluff.
Step 2: Bake the Base
Place the pressed crust in the preheated oven and bake for about 10 minutes, or until it turns a light golden brown. Keep an eye on it as it bakes; you want it just golden, not overcooked. Once done, remove it from the oven and allow it to cool completely while you prepare the filling.
Step 3: Prepare the Rhubarb
In a medium saucepan, bring water to a boil and add the chopped rhubarb. Allow it to soften in the boiling water for 10 minutes. Afterward, drain the rhubarb, letting it cool slightly before layering it onto your crust. This step ensures the rhubarb is tender, adding that delightful tartness to the Rhubarb Fluff.
Step 4: Layer the Rhubarb
Once your rhubarb is cooled and drained, spread it evenly over the cooled crust. Use a spatula to ensure an even distribution, allowing the tangy fruit to be the star of your dessert. This foundational layer provides a beautiful contrast against the creamy filling that will follow.
Step 5: Make the Filling
In a large mixing bowl, whisk together egg yolks, granulated sugar, and salt until well blended. Then slowly add the milk, stirring continuously until smooth. Finally, incorporate a bit of flour to thicken your filling. This luscious mixture will ensure a creamy base for your Rhubarb Fluff.
Step 6: Add the Filling and Bake
Pour the prepared filling over the layer of rhubarb, spreading it evenly. Return the pan to your oven and bake for 40 minutes or until the filling is set and lightly golden. You can check for doneness by gently shaking the pan; it should slightly jiggle but not be liquidy.
Step 7: Whip Up the Meringue
While your Rhubarb Fluff bakes, prepare the meringue by beating the egg whites and cream of tartar in a clean, dry mixing bowl. Whip until stiff peaks form, which should take about 5 minutes. Slowly add sugar, continuing to beat until the meringue is glossy and holds firm peaks, perfect for topping your dessert.
Step 8: Top with Meringue and Bake Again
Once the filling is baked and set, remove it from the oven and immediately spread the fluffy meringue over the filling. Use a spatula to create peaks for visual appeal. Return the dessert to the oven for an additional 10 minutes, or until the meringue is lightly golden.
Step 9: Cool and Serve
Allow your Rhubarb Fluff to cool completely on a wire rack before slicing. As it cools, the layers will set beautifully. Once cooled, cut into squares and serve, showcasing the delightful contrast of colors and textures from the creamy filling, fresh rhubarb, and fluffy meringue.
