Why it works: Chocolate and sugar are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Chocolate Cream, in Paste
Ingredients
Directions
Make the chocolate cream
Shave the required quantity of chocolate.
Boil chocolate gently in milk and sugar with a little lemon peel.
Remove the lemon peel when mixed and nearly cold.
Add egg yolks and stir constantly over heat to prevent curdling, but do not boil.
Assemble
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.
