Floating Islands

Ingredients

Directions

Poach the whites

  1. Beat the egg whites until stiff.

  2. Cook spoonfuls of the egg whites in boiling sweet milk until done, then place them on a plate.

Make the chocolate custard

  1. Dissolve the chocolate in a little hot water and add it to the milk; boil for 10 minutes.

  2. Beat the egg yolks with sugar, then pour the chocolate milk over them.

  3. Return to heat and cook until thick, but do not let it boil.

Finish and serve

  1. Remove from heat, add vanilla, and serve in glasses with the egg whites on top, chilled.

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

What each ingredient does

Egg whites
Beaten to stiff foam, then poached, giving the light, airy floating islands their structure.
Sweet milk
Forms the liquid base that poaches the whites and thickens into the custard.
Chocolate
Adds the main flavor and colors the custard.
Sugar
Sweetens the custard and balances the bitterness of the chocolate.

The step that matters

Cook the custard without letting it boil. Once the custard thickens, the egg proteins can overheat and curdle or turn grainy. Gentle heat keeps it smooth and thick.
