Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Marble Cake
Ingredients
Directions
Make the batter
Divide sponge mix between two bowls. In one, add 1 egg, cocoa and 2–3 tbsp. water, then beat until smooth and creamy.
Add second egg to the other bowl with the orange zest and 2–3 tbsp. juice. Beat to same consistency.
Bake
Spoon the mixtures into the microwave dish alternately, swirling the colors. Flatten the top and bake on high for 4–5 minutes, turning several times if the oven has no turntable.
Leave to stand 5–7 minutes.
Make the sauce and finish
Melt the chocolate and butter together on medium for 3–4 minutes, until just melted. Cool slightly and stir in the cream.
Turn cake out and place on a rack over a tray.
Coat cake generously with warm sauce.
Leave 3–4 hours to set and serve sliced.
Keep any remaining cake well wrapped.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sponge mix
- Forms the cake's main structure and crumb.
- Eggs
- Bind the batter and add structure and moisture as the cake sets.
- Cocoa powder
- Darkens one batter and adds chocolate flavour for the marbled swirl.
- Bitter chocolate
- Gives the sauce deep, bitter chocolate flavour and a glossy, setting coat.
- Butter
- Adds fat for richness and a smooth, glossy sauce.
- Orange
- Adds citrus aroma and a bright, slightly acidic flavour to one batter.
The step that matters
Baking the cake on high in the microwave. Microwaves heat quickly and unevenly, so the cake can overcook and dry or cook unevenly in places. Turning it several times when there is no turntable helps the heat spread more evenly through the batter.
Swap the orange
How well each one fits the dish's main ingredients (egg, cocoa powder, chocolate, butter, cream):
