Why it works: Chocolate and cocoa match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 165 recipes mention both. Both carry 2-ethyl-3,6-dimethylpyrazine, which smells roasted, nutty. The science ↓

Serves 8 - 10Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Heat the oven to 180°C (350°F). Grease two 20cm (8-inch) round cake tins with a little of the butter and dust them with flour.
Put the dark chocolate and 175g butter in a bowl over a pan of barely simmering water and stir until melted. Stir in the cocoa with a splash of boiling water and let cool slightly.
Whisk the eggs with the buttermilk or natural yoghurt. In a large bowl, mix the flour, golden caster sugar and bicarbonate of soda.
Stir the cooled chocolate mixture into the dry ingredients, then beat in the egg mixture until smooth. Divide the batter between the tins.
Bake for 30 to 35 minutes until risen and springy and a skewer comes out clean. Cool in the tins for 10 minutes, then turn out onto a rack to cool completely.
Drain the canned cherries, keeping 2 tbsp of the juice. Mix the kirsch with the reserved juice to make a syrup. For a non-alcoholic version, use only the reserved juice.
Whip the double cream with the icing sugar until soft peaks form, then chill. Warm the morello cherry jam with a splash of water until spreadable.
Split each cake in half horizontally. Brush the layers with syrup, spread with jam and cream, and scatter over the drained cherries. Stack the layers, then cover the top and sides with cream. Decorate with the fresh cherries if using (optional) and chill for at least 1 hour before serving.

Shared aroma: isobutyraldehyde (malty, green).
Butter and flour share little aroma chemistry, yet 122,858 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
Flavor stand-ins for the cherry
How well each one fits the dish's main ingredients (butter, chocolate, flour, sugar, cocoa, egg, buttermilk):
- Vanillabetter flavor fit
- Coconutbetter flavor fit
- Raisinbetter flavor fit
- Cherrythe original
Fit is the average pairing score against butter, chocolate, flour, sugar, cocoa, egg, buttermilk. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
