Create a dessert that will have everyone asking for the recipe with this step-by-step guide to a showstopping blackberry and bay tart. This detailed walkthrough demystifies the process of making a classic crostata, from a fragrant homemade jam to a perfect lattice crust. It’s the ideal project for a weekend baking session.
Step 1: Create the Aromatic Jam. Begin by combining 600g of blackberries with 300g of caster sugar and the juice of half a lemon. Let this mixture macerate for at least an hour. This allows the sugar to draw out the berry juices. Next, transfer the mixture to a saucepan, add two fresh bay leaves, and simmer for 10-12 minutes. Use the chilled saucer test to check for the setting point: a drop of jam on the cold plate should wrinkle when pushed. Once done, remove the bay leaves and let the jam cool completely.
Step 2: Prepare the Crumbly Pastry. In a separate bowl, beat 155g of unsalted butter with 60g of caster sugar until creamy. Whisk in one whole egg and two egg yolks. In another bowl, combine 310g of Type 00 or plain flour, a quarter teaspoon of baking powder, and half a teaspoon of fine sea salt. Add the dry ingredients to the wet and mix until a dough forms. Knead it briefly, then divide it into two pieces (one slightly larger), wrap, and chill for one hour.
Step 3: Assemble Your Crostata. Preheat your oven. Roll out the larger piece of dough and use it to line a 23cm loose-bottomed tart tin. Trim the edges and prick the base with a fork. Spoon in about 300g of your cooled homemade jam. Roll out the smaller piece of dough and cut it into eight even strips for the lattice.
Step 4: Create the Lattice and Bake. Weave the strips over the jam to create a lattice pattern, with four strips going in each direction. Trim any excess dough from the edges. Lightly brush the pastry strips with a little milk for a golden finish. Bake for 25-30 minutes, or until the pastry is beautifully browned and crisp.
Step 5: Cool and Serve. It is crucial to let the crostata cool completely in the tin before attempting to remove it. This allows the jam filling to set firmly. Once cooled, you can easily lift it out and slice it. This dessert not only tastes incredible but also showcases your baking prowess.
