Prepare the base

  1. Heat 1 quart of sweet milk to boiling.

  4. Strain the mixture through a muslin bag and divide it into 4 portions, allowing 1 cup for each.

Make the layers

  1. For one portion, mix in 1 tablespoon of chocolate wet with a little boiling water, then heat the chocolate mixture until very hot, but do not boil.

  2. In the second portion, mix in the beaten yolk of 1 egg, then heat the egg yolk mixture as above.

  3. Color the third portion with cochineal or cranberry juice.

Mold and unmold

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

What each ingredient does

Gelatin
Sets the liquid milk into a firm, sliceable dessert when chilled.
Sweet milk
Forms the creamy body of the blancmange.
Sugar
Sweetens the milk and adds body to the set dessert.
Egg yolk
Enriches the yellow layer with richness and a custard-like flavor.
Chocolate
Gives the dark layer its flavor and color.

The step that matters

Heating the gelatin mixture without boiling the chocolate and yolk portions. Gelatin must fully dissolve for a firm set, but boiling an egg yolk mixture can curdle it and grainy chocolate can separate, so keep these portions very hot without boiling.

Swap the cranberry

How well each one fits the dish's main ingredients (milk, sugar, chocolate, egg):

  1. Vanillafits better
  2. Coconutfits better
  3. Figfits better
  4. Cranberrythe original

Fit is the average pairing score against milk, sugar, chocolate, egg. Candidates are from the same food group and used in at least 100 recipes.
