Cherry and Chocolate Marble Loaf Cake

STEP 1: SOAK THE CHERRIES

Combine the chopped dried sour cherries with the kirsch (or cherry juice) and leave to soak for at least 30 minutes while you prepare everything else. Reserve any liquid that isn't absorbed – it goes into the cherry batter. Preheat the oven to 160°C fan (170°C conventional / 325°F) and grease and line the loaf tin.

STEP 2: MAKE THE BASE BATTER

Cream the softened butter and caster sugar until pale and fluffy, 3–4 minutes. Beat in the eggs one at a time. Fold in the self-raising flour, milk, vanilla and salt until just combined, stopping the moment the flour disappears – over-beating is the most common cause of a dense, low loaf, so be gentle to protect the height the judges admired. Divide the batter as evenly as you can between two bowls (weigh them if you can).

STEP 3: BUILD THE TWO HALVES TO THE SAME CONSISTENCY

This is the heart of the fix. Into the first bowl, fold the soaked cherries, their reserved soaking liquid and the cherry paste. For the chocolate half, stir the sifted cocoa into the hot milk to a smooth paste to bloom it (add the melted dark chocolate if using), cool slightly, then fold it through the second bowl. Cocoa stiffens its batter, so loosen whichever batter is thicker with a teaspoon of milk at a time until both drop off the spoon at the same rate. Matched batters marble cleanly; mismatched batters smear into a splodge.

STEP 4: LAYER, DON'T MIX

Spoon the two batters into the lined tin in alternating dollops – cherry, chocolate, cherry, chocolate – building two or three rough layers. Resist the urge to spread or smooth between dollops; the marble comes from keeping the colours distinct as they go in.

STEP 5: THE SINGLE DELIBERATE SWIRL

Push a skewer or thin knife to the bottom of the tin and draw it through the batter in one slow, continuous figure-of-eight, making just two or three passes down the length of the loaf, then stop. The fault Paul flagged came from over-dragging, which blends the two batters into a muddy splodge; a small number of confident strokes leaves a defined, readable swirl in every slice. Tap the tin on the counter once to settle.

STEP 6: BAKE FOR HEIGHT AND A CLEAN CRUMB

Bake for 50–60 minutes, until well risen, springy, and a skewer inserted into the centre (avoiding a cherry) comes out clean. If the top colours before the centre sets, tent loosely with foil. A steady, moderate oven gives the tall, even rise and the perfect texture the judges praised. Cool in the tin for 10 minutes, then turn out onto a rack and cool completely before topping.

STEP 7: MAKE THE GANACHE

Heat the cream until it just steams (do not boil). Pour over the chopped dark chocolate, leave for 2 minutes, then stir from the centre outward into a glossy emulsion. Stir in the optional teaspoon of cherry paste. Cool to a thick, spreadable, pipeable consistency – about 20–30 minutes at room temperature.

STEP 8: CHERRY MACARONS (OPTIONAL)

Sift the ground almonds and icing sugar together. Whisk the egg whites to soft peaks, add the caster sugar gradually to a stiff, glossy meringue, and beat in a little gel colour. Fold the almond mixture through until the batter ribbons and falls in a slow stream. Pipe small rounds onto a lined sheet, tap firmly, rest 30–45 minutes until a skin forms, then bake at 150°C (300°F) for 12–14 minutes. Cool fully, then sandwich with cherry jam or cherry buttercream. Work in a warm, dry room – a cold kitchen is the macaron's enemy.

STEP 9: FINISH AND SERVE

Spread or pipe the ganache generously over the top of the cooled loaf, letting it fall down the sides. Arrange the cherry macarons along the top while the ganache is still tacky. Slice with a sharp knife to reveal the corrected marble.
