Why it works: Sugar and chocolate 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 ↓
Chocolate Cream Cake
Ingredients
Directions
Make the coating
Boil water, sugar, and grated chocolate in a small saucepan until thick and velvety.
Remove from heat and stir in the egg whites without beating.
Coat and set
While hot, cover the sides and top of the cake with the mixture.
Allow it to cool; it will firm up as it does.

What each ingredient does
- Sugar
- Sweetens the coating and helps it thicken into a syrup as it boils.
- Grated chocolate
- Adds chocolate flavour and body to the coating as it melts into the syrup.
- Egg whites
- Stirred in unbeaten, they add body to the coating as it cools.
The step that matters
Coating the cake while hot. The mixture firms up as it cools, so it must be spread over the cake while still warm. If it cools first, it sets unevenly and is hard to spread smoothly. Stirring the egg whites in without beating keeps the coating smooth and glossy rather than foamy.
