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

What each ingredient does

Chocolate
Melts into the milk to give the sauce its flavour and body.
Milk
Forms the liquid base that the chocolate melts into and thins the sauce.
Egg
Thickens the sauce as it gently cooks, giving it a smooth, custard-like texture.

The step that matters

Return to the pan and whisk over low heat until the egg is cooked but not curdled.. Egg proteins set when heated, so high heat or long cooking can scramble the egg and make the sauce grainy. Gentle heat and constant whisking keep it smooth and thickened.
