Pistachio and Cherry Liqueur Cakes

STEP 1 — BAKE THE CHOCOLATE SPONGE
Preheat the oven to 180°C (350°F). Line two 33 × 23 cm (13 × 9 in) Swiss roll tins with parchment, leaving overhang. Sift the flour, cocoa, baking powder and salt together; set aside. In a stand mixer, whisk the egg whites to soft peaks, then gradually add half the caster sugar (75 g) and whisk to firm, glossy peaks. In a separate bowl, whisk the yolks with the remaining sugar until thick and pale. Fold the yolk mixture into the whites in two additions, then sift the flour-cocoa mixture over the top in three additions, folding gently with a large metal spoon — the goal is to keep as much air as possible. Divide between the two tins, spreading thinly and evenly. Bake for 12–15 minutes until the sponge springs back. Cool in the tins for 5 minutes, then turn out onto wire racks.

STEP 2 — MAKE THE CHERRY VODKA SOAK (FIX-IT CORRECTION)
While the sponge bakes, place the frozen sour cherries, granulated sugar and water in a small saucepan. Bring to a simmer over medium heat, mashing the cherries lightly with a fork to release juice. Simmer for 6–8 minutes until the liquid is syrupy and the cherries are tender. Strain through a sieve, reserving twelve whole cherries for the centres. Return the strained syrup to the pan and reduce until you have about 80 ml. Remove from the heat; let it cool slightly, then stir in the wiśniówka. Reducing fresh cherry juice into the syrup and adding a measured 45 ml of liqueur — rather than splashing neat spirit onto a finished syrup — concentrates the cherry character while balancing the alcohol presence.

STEP 3 — CUT THE SPONGE DISCS
Using a 6 cm round cutter, stamp out twenty-four discs from the two cooled sponges — you will get twelve from each tin if cut economically. Pair each disc with a partner of similar thickness; the thicker of the two pairs becomes the bottom of each cake.

STEP 4 — BRUSH THE BOTTOM SPONGES ONLY (FIX-IT CORRECTION)
Place the twelve bottom discs on a tray. Using a pastry brush, soak each one generously with the cooled cherry-vodka syrup — the sponge should be visibly damp but not flooded (about 1 1/2 teaspoons per disc). Leave the top twelve discs dry. This is the traditional wuzetka technique and prevents the assembled cake from being soggy from above as well as below.

STEP 5 — MAKE THE PISTACHIO CREAM
If using gelatine, bloom 1/4 tsp in 1 tbsp of cold water for 5 minutes, then warm gently for 10 seconds in the microwave to dissolve. In a stand mixer, whip the cold cream with the icing sugar and vanilla to soft peaks. Whisk a generous spoonful of the cream into the pistachio paste to loosen it, then fold this back into the cream in three additions. If using gelatine, drizzle it in while the mixer runs on low. Whip just to firm peaks — do not overwhip. Transfer two-thirds to a piping bag fitted with a plain round nozzle. Reserve the remainder, covered in the fridge, for the final rosettes.

STEP 6 — ASSEMBLE WITH CHERRY CENTRES (FIX-IT CORRECTION)
Working on a board, take a soaked bottom disc and pipe a ring of pistachio cream around its edge, leaving a small well in the centre. Spoon 1/4 tsp of sour cherry conserve into the well and place a single reserved poached cherry on top. Pipe a small dome of pistachio cream over the cherry. Top with a dry sponge disc, pressing very gently so the cream just reaches the edges. Repeat for all twelve. The conserve and whole cherry deliver real fruit flavour, so the cherry reads as cherry rather than as alcohol burn.

STEP 7 — CHILL THE ASSEMBLED CAKES
Transfer the assembled cakes to a tray and refrigerate for at least 30 minutes. This firms the pistachio cream so the ganache top sits cleanly without slumping the structure.

STEP 8 — MAKE THE GANACHE
Place the chopped chocolate in a heatproof bowl. Heat the cream (and corn syrup, if using) just to a simmer — the edges should be bubbling, but do not boil. Pour over the chocolate and let it sit, undisturbed, for one minute. Stir gently from the centre outwards until the ganache is glossy and uniform. Let it cool for 5–8 minutes until it is thick enough to coat the back of a spoon but still pourable.

STEP 9 — GLAZE THE TOPS
Working with the chilled cakes still on the tray, spoon about 1 1/2 teaspoons of ganache onto the top of each cake and spread to the edges with a small offset spatula. The traditional wuzetka top is shiny and just covers the edge — not a full enrobement. Tap the tray gently to settle the surface. Return to the fridge for 30 minutes to set.

STEP 10 — FINISH AND SERVE
Once the ganache is set, pipe a small rosette of the reserved pistachio cream onto each cake (a star tip looks best). Top with a fresh or glacé cherry and a pinch of chopped pistachios. Serve at cool room temperature — wuzetka is at its best when the sponge has tempered slightly and the cream is no longer fridge-cold. Best eaten the day they are assembled, though they hold beautifully in the fridge for 24 hours.
