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 ↓
German Chocolate
Ingredients
Directions
Make the chocolate base
Grate the German sweet chocolate and mix it with the egg yolks and enough water to combine.
Place the mixture in a chocolate boiler with ½ pint of hot water and stir well.
Boil for 5 minutes, then add 1 quart of boiling milk.
Finish and serve
Beat the egg whites to a stiff froth and stir them in while mixing continuously.
Serve immediately after adding the egg whites.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- German sweet chocolate
- Provides the main chocolate flavour and body of the drink.
- Egg yolks
- Thicken the mixture and add richness as they combine with the chocolate.
- Milk
- Adds creaminess and dilutes the chocolate into a drinkable consistency.
- Egg whites
- Whipped to a stiff froth, they add a light, airy foam to the top of the drink.
The step that matters
Adding the beaten egg whites. Egg whites hold air only when beaten to a stiff froth, and folding them in while mixing continuously keeps the foam distributed rather than deflating or clumping, while serving immediately preserves that airy texture.
