Ingredients and Preparation

For the Raspberry Puree

• 2 cups fresh or frozen raspberries (about 250g)
• Optional: a few tablespoons of water for blending

For the Shortbread Crust

• 2¼ cups (281g) all-purpose flour
• ½ cup (100g) granulated sugar
• 1 tablespoon corn starch
• ¼ teaspoon salt
• 1 cup (226g) unsalted butter, melted

For the Lemon Raspberry Filling

• 1½ cups (300g) granulated sugar
• ⅓ cup (40g) corn starch
• 6 large eggs
• ¼ cup thick raspberry puree (from step one)
• ¾ cup (180ml) freshly squeezed lemon juice

Optional Savory Swap (if recipe had bacon)

• ½ cup finely chopped grilled chicken breast or roasted beef (only for creative variations)

Tools You’ll Need

• 9×13-inch baking pan
• Parchment paper
• Mixing bowls
• Fine-mesh strainer or sieve
• Blender or food processor
• Saucepan
• Whisk

Prep Notes:

• Line the baking pan with parchment, leaving some overhang for easy lifting.
• If using frozen raspberries, thaw them completely and discard extra juice.
• Use fresh lemon juice rather than bottled for the most authentic taste.

Step-by-Step Instructions

Step 1: Prepare the Raspberry Puree

• Blend the raspberries in a blender or food processor until smooth.
• Pour the mixture through a fine-mesh strainer to remove seeds.
• Transfer the seedless puree to a saucepan and simmer over medium-low heat.
• Stir frequently and cook until reduced to a thick ¼ cup. This may take 15–20 minutes.
• Set aside to cool completely before using.

Step 2: Make the Shortbread Crust

• Preheat your oven to 325°F (160°C).
• In a large mixing bowl, combine the flour, granulated sugar, cornstarch, and salt.
• Stir in the melted butter and mix until a crumbly dough forms.
• Press the dough evenly into the prepared pan, creating a slight edge up the sides.
• Bake for 20–25 minutes, or until the top appears lightly golden and set.
• Remove from the oven and let cool slightly while you prepare the filling.

Step 3: Prepare the Lemon Raspberry Filling

• In a medium bowl, whisk the sugar and cornstarch to break up any lumps.
• Add the eggs one at a time, whisking thoroughly after each addition.
• Stir in the cooled raspberry puree and lemon juice. Whisk until smooth and evenly mixed.
• Optional: If making a savory version, scatter small cooked chicken or beef pieces over the crust before adding the filling.

Step 4: Bake the Bars

• Pour the filling over the partially cooled crust and gently smooth the top.
• Bake again at 325°F for 20–25 minutes, or until the edges are firm and the center jiggles slightly when tapped.
• Do not overbake, as the filling will continue to set as it cools.

Step 5: Cool and Chill

• Allow the bars to cool at room temperature for 1–2 hours.
• Then, transfer them to the refrigerator and chill for at least 2 more hours, or overnight.
• This ensures the filling is firm enough to slice cleanly.

Step 6: Slice and Serve

• Once fully chilled, lift the bars out of the pan using the parchment paper.
• Use a sharp knife to cut into squares or rectangles, wiping the blade clean between cuts.
• Dust with powdered sugar just before serving if desired.

Beginner Tips and Notes

• Reduce the raspberry puree properly: This step concentrates the flavor and thickens the texture. Don’t skip it, or your bars may turn out watery.
• Use parchment paper: It makes removing the bars from the pan and slicing them cleanly much easier.
• Chill thoroughly: Letting the bars firm up in the fridge ensures neat slices and a stable filling.
• Test the jiggle: The center of the bars should wobble slightly but not slosh when they’re ready to come out of the oven.
• Try it without seeds: Always strain your raspberry puree unless you like a bit of crunch in the filling.
• Do not use bottled lemon juice: Fresh lemons make a significant difference in flavor.
• Optional savory experiment: If you’re feeling adventurous and want to explore a sweet-savory contrast, a small amount of cooked meat in the crust layer adds intrigue. Use grilled chicken breast or a lightly seasoned beef roast—only as a creative twist.
• Crust tip: You can prick the hot crust with a fork before pouring in the filling. This helps the filling bond more securely with the base.

Serving Suggestions

• Chilled and clean: Serve cold from the fridge for the most satisfying texture and taste.
• Powdered sugar topping: A light dusting just before serving adds visual appeal and a sweet finish.
• Fresh raspberries on top: Add a few fresh berries on each piece for a gourmet presentation.
• Whipped cream or mascarpone: Serve with a small dollop of cream to balance the tart lemon.
• Citrus zest garnish: A bit of lemon or orange zest adds brightness and extra aroma.
• Plated dessert: Serve alongside a scoop of vanilla bean ice cream or a drizzle of raspberry coulis.
• On a brunch spread: These bars are great when paired with other fruity items like fruit salad, yogurt parfaits, or mini muffins.
• With drinks: Match them with a hot cup of herbal tea (like mint or chamomile), or iced green tea with honey and lemon.
