Why it works: Cocoa and milk work together. They rank in the top 10% of all ingredient pairs, and cooks put them together in 643 recipes. Both carry methyl 2-methylbutyrate, which smells fruity, apple. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg white
- Whipped to stiff foam, it gives the drink its light, airy structure.
- Cold milk
- Provides the liquid base and moisture that the whipped white is folded into.
- Sugar
- Adds sweetness and helps stabilise the whipped egg white foam.
- Breakfast cocoa
- Supplies the chocolate flavour and colour to the drink.
The step that matters
Beat the egg white until stiff. Egg white foam only holds air when it is beaten enough to form stiff peaks. Under-beaten whites collapse quickly, so the top layer will sink into the milk instead of staying light.
Swap the cocoa
How well each one fits the dish's main ingredients (egg, sugar, milk):
- Pecansfits about as well
- Almondfits about as well
- Cocoathe original
- Walnutfits about as well
Fit is the average pairing score against egg, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
