Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Custard Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the batter

  1. Preheat the oven to 350°F (175°C).

  2. In a large bowl, cream together the sugar and melted butter.

  3. Add the beaten egg yolks and mix well.

  4. In another bowl, combine the flour, baking soda, and cream of tartar.

  5. Gradually add the dry ingredients to the wet mixture, alternating with the milk.

  6. Fold in the beaten egg whites gently until combined.

  7. Pour the batter into a greased cake pan and bake for 25-30 minutes.

Make the custard

  1. For the custard, heat ½ pint of milk in a saucepan.

  2. In a bowl, whisk together 2 eggs and sweeten to taste.

  3. Slowly add the warm milk to the egg mixture, stirring constantly.

  4. Add vanilla extract for flavor.

  5. Bake the custard in pie plates until set.

Assemble

  1. Once the cake is cool, layer the custard between the cake layers.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
Egg yolks and whites provide structure and richness to the cake and set the custard.
Flour
Forms the structure of the cake batter.
Butter
Adds fat for a tender crumb and rich flavor.
Sugar
Sweetens the cake and helps it brown and stay moist.
Baking soda
Reacts with cream of tartar to lift the batter as it bakes.
Cream of tartar
Acidifies the batter so baking soda can react and help the cake rise.

The step that matters

Bake the custard until set. Custard is egg protein thickened by gentle heat. Overbaking or high heat makes eggs curdle and turn grainy or watery, so bake only until the centre barely wobbles.
