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

  1. Place 1 gill of water, 1-1/2 cupfuls sugar, and 1/2 cup grated chocolate in a small saucepan over heat.

  2. Boil until thick and velvety.

  3. Remove from heat and add the whites of 2 eggs without beating.

  4. Use while hot to cover the top and sides of the cake.

  5. As it cools, it firms.

Make and bake the cake

  1. In a bowl, combine six eggs and 3 cupfuls sugar; beat for 5 minutes.

  2. Add 4 cupfuls flour, sifted, along with 2 teaspoonfuls baking powder, pinch of salt, 1 cupful cold water, and 1 teaspoonful lemon extract.

  3. Bake in a shallow square cake pan in a quick, steady oven for 35 minutes.

Ice and finish

  1. While the cake is still hot, prepare clear icing: mix 1 cupful sugar, 1 tablespoonful lemon juice, and whites of 2 eggs until smooth.

  2. Pour icing over the cake.

  3. If the cake is not hot enough to dry the icing, place it in the mouth of a moderately warm oven.

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.
