Method
Sift the all-purpose flour, cornstarch, and salt together into a medium bowl to ensure even distribution and remove lumps.
In a stand mixer fitted with the paddle attachment, beat the softened butter, 90g icing sugar, and vanilla bean paste on medium-low speed just until smooth and combined. Do not aerate or whip until fluffy, as this causes the cookies to spread.
Add the dry ingredients to the butter mixture. Mix on low speed briefly until the dough starts to clump together. Finish bringing the dough together by hand to avoid overworking the gluten.
Roll the dough out between two sheets of parchment paper to a thickness of 6mm (1/4 inch). Slide the parchment onto a baking sheet and refrigerate for at least 30 minutes to firm up.
Preheat oven to 160°C/320°F. Remove dough from fridge, peel off top parchment, and cut into rounds using a 6cm cutter. Arrange rounds on a lined baking sheet with 2cm spacing. Chill the cut rounds again for 15 minutes before baking.
Bake for 12-15 minutes at 160°C/320°F until the edges are barely set and very pale golden. They should remain mostly pale. Allow to cool completely on the tray before moving, as they are very fragile when hot.
While shortbread cools, prepare the cream. Place cold mascarpone, cold heavy cream, 40g icing sugar, and lemon zest in a chilled bowl. Whip until stiff peaks form.
Gently fold the 100g of finely diced strawberries into the cream mixture with a spatula. Ensure the strawberry pieces were patted dry to prevent the cream from seizing or weeping.
Transfer the strawberry cream to a piping bag with a star nozzle. Pipe a generous rosette or mound of cream onto each cooled shortbread round.
Top each cream mound with a fresh strawberry half and a small mint leaf. Serve immediately.
Chef's Notes
- To achieve the 'sablé' (sandy) texture, use cornstarch in the dough; it inhibits gluten formation and creates a tender crumb.
- Do not over-bake. Shortbread should be pale. If it turns brown, the delicate butter flavor changes to a caramel flavor, which is delicious but not intended for this profile.
- Assemble these as close to serving time as possible. The moisture from the cream will eventually soften the crisp shortbread (though they are still delicious after 2 hours).
Storage
Refrigerator: 2 days — Store components separately. Assembled tarts soften within 4 hours.
Freezer: 1 month — Raw dough discs can be frozen. Do not freeze the strawberry cream.
Troubleshooting
Shortbread spread and lost its shape
Cause: Dough was too warm when entering the oven or too much air was incorporated during creaming
Fix: Use a round cutter to trim the edges while the cookies are still hot and soft
Prevention: Chill the cut rounds thoroughly before baking; mix butter and sugar only until combined, not fluffy
Cream filling is runny
Cause: Ingredients were too warm or strawberries added too much moisture
Fix: Chill the mixture for 20 minutes to firm up; if still runny, serve as a 'dip' rather than piped
Prevention: Ensure mascarpone and cream are fridge-cold; pat diced strawberries very dry
Cultural Context
Shortbread originated in Scotland, evolving from medieval biscuit bread into a luxury treat rich in butter. This variation incorporates French pâtisserie techniques (the sablé dough and chantilly cream) to create a lighter, summer-focused dessert.
