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

What each ingredient does

Gelatine
Sets the liquid as it cools, giving the layers a firm, sliceable body.
Milk
Forms the creamy liquid base that the gelatine sets into each layer.
Egg yolks
Enrich the second layer with fat and richness, giving it a softer, custard-like texture.
Chocolate
Adds bitter flavor and a deep brown color to the third layer.
Sugar
Adds sweetness to balance the milk and chocolate flavors.

The step that matters

Let each layer almost cool before pouring the next. A warm layer melts the one beneath it, so the colours blur together instead of forming distinct bands. Gelatine sets as it cools, so the timing controls how cleanly the layers stay separate.
