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
Ingredients
Directions
Make the chocolate icing
Place 1 gill of water, 1-1/2 cupfuls sugar, and 1/2 cup grated chocolate in a small saucepan over heat.
Boil until thick and velvety.
Remove from heat and add the whites of 2 eggs without beating.
Use while hot to cover the top and sides of the cake.
As it cools, it firms.
Make and bake the cake
In a bowl, combine six eggs and 3 cupfuls sugar; beat for 5 minutes.
Add 4 cupfuls flour, sifted, along with 2 teaspoonfuls baking powder, pinch of salt, 1 cupful cold water, and 1 teaspoonful lemon extract.
Bake in a shallow square cake pan in a quick, steady oven for 35 minutes.
Ice and finish
While the cake is still hot, prepare clear icing: mix 1 cupful sugar, 1 tablespoonful lemon juice, and whites of 2 eggs until smooth.
Pour icing over the cake.
If the cake is not hot enough to dry the icing, place it in the mouth of a moderately warm oven.
Nutrition, whole recipe (rough)
Counts 6 of 7 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Eggs
- Whipped with sugar to trap air, giving the cake its light, risen structure.
- Flour
- Forms the cake's structure once its proteins set during baking.
- Baking powder
- Releases gas during baking, helping the cake rise and turn lighter.
- Sugar
- Sweetens the cake and helps the icings set glossy and firm as they cool.
- Grated chocolate
- Provides the chocolate flavour and thickens the boiled icing as it cooks.
- Lemon juice
- Adds acidity that brightens the sweetness of the clear icing.
The step that matters
Adding the egg whites to the hot chocolate icing without beating. Stirring the whites in gently over residual heat keeps the icing smooth and glossy; beating or cooling it too early can make it grainy or dull, and it firms as it cools.
