Why it works: Vanilla and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,287 recipes. Both carry 4-methoxybenzaldehyde, which smells sweet, anise. The science ↓

Dark Chocolate Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the chocolate base

  1. Melt the chocolate over hot water.

  2. Gradually add the milk, stirring until smooth.

  3. Add the sugar and egg, cooking until thickened while stirring constantly.

  4. Cool the mixture and add vanilla.

Make the batter

  1. Cream the butter and add the sugar and beaten egg yolks.

  2. Incorporate the chocolate mixture thoroughly.

  3. Mix and sift the dry ingredients, adding them alternately with the sour milk.

  4. Fold in the stiffly beaten egg whites.

Bake

  1. Pour into greased layer pans and bake at 350°F (175°C) for 35 to 40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Dark chocolate
Provides the main chocolate flavour and a rich, dark colour to the cake.
Eggs
Yolks add richness and binding, while whipped whites lighten the batter and add structure.
Flour
Forms the cake's structure once its proteins set during baking.
Butter
Adds fat for tender texture and rich flavour.
Light brown sugar
Adds sweetness and moisture, and contributes to the cake's browning and flavour.
Baking soda
Reacts with the sour milk to produce gas that makes the cake rise.

The step that matters

Fold in the stiffly beaten egg whites. Whipped whites trap air that lightens the batter. Folding gently keeps that air in; vigorous stirring deflates it and leaves a dense cake.
