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 ↓

Chocolate Custard

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the chocolate base

  1. Break the chocolate into a dozen pieces and place it over boiling water, covered with a little milk.

  2. Mash the chocolate and stir until smooth.

  3. Add the remaining milk and mix well.

Make the custard and bake

  1. In a separate bowl, beat the eggs and sugar together.

  2. Flavor the egg mixture with vanilla.

  3. Combine the chocolate mixture with the egg mixture and pour into a baking dish.

  4. Bake in a slow oven at 300°F (150°C) until set.

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

What each ingredient does

Eggs
Set the custard as they cook, giving it structure and a firm, sliceable body.
Sweetened chocolate
Provides the chocolate flavor and, as it melts into the milk, a rich, smooth body.
Milk
Forms the liquid base that thins the chocolate and gives the custard its creamy moisture.
Sugar
Sweetens the custard and helps soften the set texture of the eggs.

The step that matters

Bake until just set. Egg proteins set with heat, and overbaking squeezes out liquid and makes the custard grainy or watery. Stop when the center barely wobbles, as it will firm as it cools.
