Coffee Custard

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.

Prepare

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

  2. Bring the milk nearly to a boil.

  3. Beat the eggs in a bowl.

Make the custard

  1. Pour the hot milk over the beaten eggs, stirring constantly.

  2. Add sugar and coffee essence to taste.

  3. Pour the mixture into greased ramekin cases.

Bake and serve

  1. Bake until set, about 20 minutes.

  2. Serve hot or cold.

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 tender body.
Milk
Provides the liquid base and creamy richness that the eggs set into custard.
Sugar
Adds sweetness and balances the coffee flavour.

The step that matters

Pouring the hot milk over the beaten eggs. Adding hot milk slowly while stirring constantly gradually warms the eggs. Pouring too fast can scramble them, leaving a grainy texture instead of a smooth custard.
