Elevate your pâtisserie skills with this refined take on a continental classic. This Black Forest Roulade is a sophisticated study in balance, pairing a light-as-air, cocoa-rich chocolate génoise with the tart brightness of cherries.
Inside, a velvet-smooth vanilla Chantilly cream provides a cool, creamy contrast to the fruit, while a coating of indulgent dark chocolate ganache—textured to mimic natural tree bark—adds a final layer of silken richness. Far beyond a simple Swiss roll, this recipe serves as a technical masterclass, guiding you through the essential ‘four-stage sabayon’ and professional tightening techniques to ensure a flawless, bakery-standard spiral every time.
Ingredients
Cherry Compote
-
Frozen Morello ‘Sour’ Cherries: These provide the essential tartness that defines a true Black Forest dessert. Their high acidity cuts through the richness of the chocolate and cream, offering a bright, ‘sharp’ fruit profile.
-
Frozen Dark Sweet Cherries: Selected for their deep colour and natural sugars, these cherries add a jammy sweetness and a plump, meaty texture to the compote, creating a multi-dimensional fruit filling.
-
Caster Sugar: Used to macerate the fruit and balance the natural acidity of the Morello cherries. It dissolves quickly during the simmering process to create a clear, smooth syrup.
-
Pectin: A natural setting agent that transforms the cherry juices into a delicate, thickened glaze. This ensures the compote stays in place within the roulade rather than soaking into the sponge.
-
Lemon Juice: The addition of citrus not only prevents the sugar from crystallising but also activates the pectin and heightens the vibrant, ruby-red colour of the cherries.
Chocolate Génoise
-
Whole Eggs: The engine of the génoise. When whisked with sugar, the proteins in the eggs trap air to create a stable foam; this is the sole leavening agent for the sponge, providing its characteristic lift and flexible structure.
-
Caster Sugar: Beyond adding sweetness, the fine crystals of caster sugar assist in stabilising the egg foam during the whisking process, ensuring the sponge is light and airy rather than dense.
-
Plain Flour (9-11% Protein): A specific protein range is essential for a roulade. This level of gluten provides enough strength to prevent the sponge from tearing during the roll, while remaining low enough to ensure a delicate, “melt-in-the-mouth” crumb.
-
Cocoa Powder: We use a high-quality, Dutch-processed cocoa to provide a deep, bittersweet chocolate profile and a rich mahogany colour. Its fine particles are sifted into the flour to ensure they incorporate seamlessly without deflating the aerated egg mixture.

Storing Black Forest Roulade
-
Refrigeration: The finished roulade will keep beautifully for up to 3 days in the fridge. For the best texture and flavour, I recommend removing it from the refrigerator 30 minutes before serving to allow the ganache and sponge to soften slightly at room temperature.
-
Freezing: This cake is excellent for preparing in advance. I typically freeze the roulade prior to decorating; simply keep it wrapped in the original parchment paper until solid, then add a layer of cling film (plastic wrap) to prevent freezer burn.
-
Thawing & Finishing: When you are ready to serve, thaw the roulade at room temperature for 30 minutes before applying the ganache decoration. Once decorated, allow the cake to finish thawing completely in the fridge for a minimum of 3 hours before slicing.
What is Pectin?
Pectin is a naturally occurring polysaccharide found within the cell walls of fruits and vegetables, providing them with their structural integrity. Commercially, it is most commonly derived from citrus peels and apple pomace. In the culinary world, it serves as a highly effective natural gelling agent and thickener, essential not only for traditional jams but also for refined compotes, glazes, and fluid gels.
In this recipe, the addition of pectin is vital for several reasons:
-
Structural Stability: It allows us to control the viscosity of the compote. By creating a delicate gel, pectin ensures the fruit juices are “locked in,” preventing them from bleeding into the vanilla Chantilly or soaking into the delicate chocolate génoise.
-
Visual Appeal: Pectin helps to preserve the natural pigments of the cherries, enhancing their vibrant, ruby-red brightness and providing a professional, high-gloss finish to the filling.
-
Flavour Preservation: Because pectin allows the compote to thicken quickly, it reduces the necessary boiling time. This shorter cooking window preserves the fresh, bright profile of the fruit rather than resulting in a “stewed” or muted flavour.
-
Dietary Inclusive: As a plant-based derivative, pectin is a completely vegan-friendly alternative to gelatine, making it a versatile choice for modern pâtisserie.

Method
- Into a mixing bowl, whisk together sugar and pectin until all the pectin is dispersed and clump free.
- Into a saucepan on a medium heat add in the frozen cherry, stirring occasionally allowing the natural juice to release and come to a boil.When at a boil, while stirring add in the sugar-pectin mix and stir until the sugar completely dissolves. Bring back to a boil and boil for 2 minutes.Turn of the heat, stir in the lemon juice and decant into a container and surface wrap with cling film (plastic wrap), cover with a lid and into the fridge for at least 3 hours to set.
- Into a clean saucepan bring whipping cream to a boil.
- Pour the hot cream over the chocolate and let it sit for 30 seconds.With a spatula mix until all the chocolate has melted and you have a smooth and silky liquid ganache.Decant into a container, surface wrap with cling film and cover with a lid. Leave to set at room temperature for a few hours minimum.
- Preheat the oven to 160℃ (320℉) and line a 40x30cm baking tray with a silicon mat
- Into a mixing bowl, sift flour and cocoa powder to remove any clumps and set aside.
- Next make a cold sabayon, crack the eggs into a bowl add the sugar and with an electric whisk, whisk starting on a low speed gradually increasing to high until the eggs have approximately tripled in volume, have become light and pale and have a thick consistency. This will take around 5-10 minutes.
- In ⅓ increments gently fold in the dry ingredients until it has a been combined. Be careful not to knock out the air from the sabayon.
- Pour the mixture into the baking tray and with a palette knife spread evenly. Place the tray into the oven and bake for 9-12 minutes.
- Once baked, leave to cool 5-10 minutes until the point it is still warm but can be handled with your bare hands. Turn the sponge out on to a piece of greaseproof paper and peel bake the silicon mat. Cover with another piece of greaseproof paper and gently roll into the shape of a roulade and set aside to cool completely. Approximately 30-45minutes.
- Into a mixing bowl add whipping cream and icing sugar. Split and scrape seed of a vanilla pod and add to the cream. Whisk the cream on a medium to high speed until the cream has reached medium peaks.
- Into separate piping bags fill the vanilla Chantilly and cherry compote.
- Unravel the sponge remove the top piece of baking paper but leave it resting on the bottom piece. Pipe the Chantilly in a zig zag motion across the surface of the sponge leaving about an inch gap around the edges. Using a palette knife, spread the Chantilly cream in an even layer across the entire surface of the sponge, ensuring a smooth finish right to the edges.
- Repeat the process with the cherry compote, ensuring you do not press the fruit into the Chantilly, but rather allow it to sit delicately upon the surface to maintain the distinct, layered contrast between the cream and the cherries.
- Starting with the edge closest to you, use the parchment paper to lift and guide the sponge into a tight, even spiral. Once rolled, place a long ruler against the base of the cylinder, while holding the bottom layer of paper, push the ruler firmly inward to 'tuck' and tension the roll.
- Set the roulade into the freezer overnight.
- Remove the roulade from the freezer and, using a sharp knife, trim the ends to reveal the clean, spiralled interior. Collect a small amount of ganache on the tip of your palette knife and spread it across the surface, working your way around the cylinder. By applying the ganache in short, overlapping strokes, you will create a rustic, textured finish that beautifully mimics the appearance of natural tree bark.
- Leave in the fridge to defrost until you are ready to serve but for a minumum of 2 hours.
