Why it works: Chocolate and sugar are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Plain Chocolate Icing
Ingredients
Directions
Make the icing
Put four tablespoonfuls of scraped chocolate into a shallow pan and place it where it will melt gradually, but not scorch.
When melted, stir in three tablespoonfuls of milk or cream and one tablespoonful of water.
Mix all well together, and add one scant teacupful of sugar. Boil about five minutes.
Assemble and set
While hot, and when the cakes are nearly cold, spread some evenly over the surface of one of the cakes.
Put a second layer on top, alternating the mixture and cakes.
Cover top and sides, and set in a warm oven to harden.
Nutrition, whole recipe (rough)
Counts 3 of 4 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides the main flavour and, as it cools, sets into a firm, glossy coating.
- Sugar
- Sweetens the icing and helps it thicken as it boils and cools.
- Milk
- Adds moisture and softness, loosening the chocolate into a spreadable mixture.
The step that matters
Melt the chocolate gently. Chocolate scorches easily under direct, high heat, which makes it grainy and bitter. Slow, gentle melting keeps it smooth so the icing sets evenly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
