Ingredients

Step-by-step Instructions

Step 1: Preparing the Rhubarb and Raspberry Jam

Start by preparing the herbs and fruits for the filling. Gather your fresh rhubarb stalks, which are known for their tart flavor and striking crimson hue. Rinse them thoroughly under cold running water to remove any dirt or residual pesticides. Use a vegetable peeler to thinly peel the outer fibrous layer, especially if you notice a tough or stringy surface. This peeling step ensures a more tender and palatable filling, eliminating any fibrous bits that could affect texture.

Once peeled, chop the rhubarb into uniformly small pieces, roughly 1-2 centimeters in size. This small chopping size helps the rhubarb break down more evenly during cooking, resulting in a smoother jam-like consistency. Place the chopped rhubarb into a large, sturdy mixing bowl.

Next, coarsely chop the fresh raspberries, ensuring their delicate texture is preserved while breaking them into manageable bits. Add these berries directly into the bowl containing rhubarb.

Incorporate the sugar—specifically 400 grams—into the mixture. Gently toss the fruit and sugar together, ensuring that each piece is coated with sugar. Cover the bowl tightly with plastic wrap or a silicone lid to prevent moisture loss and set it aside in the fridge for at least two hours. During this maceration phase, the fruit juices will be released, softening the fruit and forming a naturally sweet syrup—crucial for depth of flavor and proper setting of the filling.

Step 2: Making the Pastry Dough

While the fruit macerates, move on to preparing the pastry dough. Use a food processor to combine the dry ingredients—250 grams of all-purpose flour and 90 grams of sugar—timing the pulse to distribute evenly.

Add the cold, cubed butter to the food processor. Pulse several times until the mixture resembles coarse crumbs with small pea-sized bits of butter throughout. The cold butter is essential to ensure a flaky, tender crust that melts in the mouth.

Transfer this crumbly mixture onto a lightly floured work surface. Create a well in the center and pour in 15 grams of Millefiori honey—the honey will add a subtle floral note and enhance the crust’s richness—and the lightly beaten egg (about 55 grams). Knead gently with your fingertips, incorporating the ingredients until the dough comes together into a smooth, pliable ball.

Wrap the dough tightly in plastic wrap and refrigerate for at least one hour. Resting allows gluten development, which contributes to a tender, shortcrust consistency, and the cold temperature solidifies the butter for flakiness.

Step 3: Assembling the Crostata

Cooking the Fruit Filling

Once the maceration time has passed, transfer the fruit mixture into a heavy-bottomed saucepan. Cook over medium heat, stirring gently and frequently to prevent sticking and burning. During this process, moisture from the fruit evaporates slowly, intensifying the flavors and thickening the mixture.

Continue cooking until the mixture reaches a jam-like consistency—thick and glossy, with no excess liquid left. This typically takes about 15-20 minutes, but keep a close eye, as sugar content and fruit moisture vary.

Remove the pan from heat and allow the fruit filling to cool completely. This is critical because a hot filling can cause the pastry crust to become soggy or deform during assembly.

Rolling the Pastry

While the filling cools, retrieve your rested dough from the refrigerator. Lightly flour your work surface and rolling pin to prevent sticking. Roll the dough into a circle approximately 3-4 millimeters thick and roughly 30 centimeters in diameter, ensuring it is slightly larger than your tart pan to allow for an overhang.

Gently transfer the rolled dough onto the tart pan, either by draping it over the rolling pin or folding it in quarters before placing it in the pan. Press gently into the pan’s corners and sides, smoothing out any cracks or air pockets. Trim excess dough from the edges with a sharp knife or use your fingers to fold the dough for a decorative border.

Pour the cooled fruit filling into the pastry shell, spreading evenly with a spatula or back of a spoon. Distribute it uniformly to create an even surface, preparing it for baking.

Step 4: Baking the Crostata

Preheat your oven to 180°C (350°F), setting it to standard convection heat if available for uniform baking. Place your assembled crostata on the middle rack and bake for approximately 30-35 minutes.

During baking, watch for the crust becoming golden brown—this indicates doneness—and bubbles in the filling. The aroma of baked fruit and buttery pastry will alert you to nearing completion.

Once baked, remove the crostata from the oven and transfer it to a cooling rack. Allow it to cool entirely; this step is vital to set the filling and achieve clean slices upon serving. Cooling also helps prevent the crust from crumbling when removed from the tart pan.

Step 5: Preparing the Italian Meringue

Making the Sugar Syrup

In a small, heavy-bottomed saucepan, combine 30 grams of water and 100 grams of granulated sugar. Place over medium heat, stirring gently until the sugar dissolves completely.

Attach a digital or candy thermometer to monitor the temperature precisely. Continue heating, without stirring, until the syrup reaches 110°C (230°F). This initial stage, the soft-ball stage, ensures the sugar is cooked enough for a stable meringue.

Once at temperature, remove the syrup from heat. Keep it warm while you prepare the egg whites.

Whipping Egg Whites

In a clean stand mixer bowl, whip the egg whites (about 50 grams, or 2 large whites) on medium-high speed. Beat until soft peaks form—that is, when the whites hold a droplet shape but curl at the tips when lifted.

With the mixer running, slowly pour the hot sugar syrup into the egg whites in a thin, steady stream. This process must be done carefully to prevent splattering and to ensure smooth incorporation.

Continue beating until the mixture thickens, becomes glossy, and reaches room temperature. The final meringue should hold stiff peaks but remain light and airy, perfect for a fluffy topping that complements the rich land and fruit flavors.

Step 6: Assembling and Decorating the Crostata

Once the crostata has cooled, spread the fluffy Italian meringue over the top. Use a spatula or piping bag for decorative touches. For a rustic look, a simple spreading with a spatula is sufficient; for more intricate designs, piping patterns or rosettes can be added.

For an elegant finale, sprinkle some reserved rhubarb fibers or finely chopped fruit on top of the meringue, creating a striking contrast of color and texture.

Allow the meringue to set at room temperature for at least 20-30 minutes. The meringue can be briefly browned with a kitchen torch for a toasted look if desired, adding depth and visual appeal.

Enjoying the Crostata

Serve slices at room temperature for optimal flavor and texture. The combination of buttery crust, intense fruit filling, and airy meringue creates a multi-layered sensory experience. Paired with a cup of tea or a glass of dessert wine, this crostata makes for an unforgettable indulgence.

Preparation Tips

• Use fresh fruits: The quality of rhubarb and raspberries significantly affects flavor. Opt for organic or freshly picked when possible.
• Manage moisture: Excess liquid in filling can lead to soggy crust. Cooking the filling till jam-like and cooling thoroughly mitigates this risk.
• Work with cold ingredients: Cold butter and dough produce flaky pastry. Avoid overworking the dough to prevent gluten development and toughness.
• Temperature control is key: Monitoring sugar syrup is crucial for perfect meringue stability and texture.
• Test the crust: Baste the crust with egg wash or sprinkle with sugar for a glossy finish if desired before baking.

Nutritional Information

• Light fruit preserves or coulis for drizzling

Improvements and Customizations

• Gluten-Free: Substitute with a blend of gluten-free flours such as rice, almond, or oat flour.
• Vegan: Use plant-based butter and aquafaba in place of eggs for the meringue, or opt for a fruit topping without meringue.
• Enhanced Flavors: Incorporate spices such as cinnamon, cardamom, or ginger into the fruit filling for warmth.
• Texture Boost: Add chopped nuts or oats into the crust for crunch.

Save and Store

Store the crostata in an airtight container in the refrigerator for up to 2 days. The meringue may soften slightly after refrigeration but will still be delicious. For best results, rewarm the crostata briefly in a low oven or gently re-toast the slices for a crispier bite. To extend shelf life, you can freeze individual slices wrapped tightly in plastic wrap and then foil for up to 1 month; thaw in the refrigerator before serving.

FAQs

Can I prepare the crostata in advance?

Yes, you can prepare the crust and fruit filling a day ahead and assemble just before baking. The meringue is best added after baking to maintain its texture and structure.

Can I use frozen raspberries or rhubarb?

Frozen fruits can be used, but ensure they are thoroughly thawed and drained to avoid excess moisture. Adjust cooking times accordingly.

Is it necessary to peel the rhubarb?

Peeled rhubarb yields a milder, more tender filling, but you can skip peeling if the stalks are tender and the fibrous layer is thin.

What if I don’t have a sugar thermometer?

Monitor the sugar syrup closely for the classic soft-ball stage: drop a small amount into cold water, and it should form a soft, flexible ball that flattens when removed from water. Practice makes perfect.
