Chocolate Cream, in Paste

Ingredients

Directions

Make the chocolate cream

  1. Shave the required quantity of chocolate.

  2. Boil chocolate gently in milk and sugar with a little lemon peel.

  3. Remove the lemon peel when mixed and nearly cold.

  4. Add egg yolks and stir constantly over heat to prevent curdling, but do not boil.

Assemble

  1. Pour the uniform mixture onto a crust of puff pastry.

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

What each ingredient does

Egg yolks
Thicken the cream as they set gently with heat, giving it a smooth, rich body.
Chocolate
Provides the main flavour and, as it melts into the milk, colours and firms the cream.
Milk
Forms the liquid base that carries the chocolate and sugar and gives the cream its softness.
Sugar
Adds sweetness and balances the bitterness of the chocolate.
Puff pastry
Forms the crisp base that holds the cream.

The step that matters

Add egg yolks and stir constantly over heat. Egg yolk proteins thicken the cream when gently heated, but if the mixture gets too hot or is left unstirred, the proteins scramble and curdle. Keeping it below boiling and stirring constantly keeps the cream smooth.

Swap the lemon
