Custard in Cups

Ingredients

Directions

Flavor the milk

  1. Boil the milk in an enamelled saucepan with the sugar and your chosen flavoring.

  2. Let the milk steep by the side of the fire until well flavored.

  3. Whisk the eggs in a bowl.

  4. Bring the milk to a boiling point.

  5. Strain the milk into a basin.

Make the custard

  1. Once the milk has cooled slightly, stir in the eggs.

  2. Strain the mixture into a jug.

  3. Place the jug in a saucepan of boiling water.

  4. Stir the custard continuously until it thickens, ensuring it does not boil to avoid curdling.

Finish

  1. Remove the custard from heat.

  2. Stir in the brandy if desired.

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

What each ingredient does

Milk
Forms the liquid base that gives the custard its body and moisture.
Eggs
Set as they heat, thickening the milk into a creamy custard.
Sugar
Sweetens the custard and balances the flavoring.
Cinnamon or vanilla extract
Adds aroma and flavor to the milk as it steeps.

The step that matters

Stir the custard continuously without letting it boil. Egg proteins set gently as the custard warms. If it overheats or boils, the proteins tighten too quickly and squeeze out water, so the custard curdles and turns grainy instead of smooth.
