The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: beta-damascenone (apple, rose).

Sugar and milk barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Cocoa
Provides the chocolate flavour and dark colour of the junket.
Sugar
Adds sweetness and helps balance the bitterness of the cocoa.
Milk
Forms the liquid base and supplies the proteins that set into a soft curd.
Essence of pepsin
An enzyme that clots the milk proteins, setting the mixture into a soft custard-like junket.

The step that matters

Adding the pepsin at lukewarm temperature. Pepsin works best at about body temperature. If the milk is too hot, the enzyme is destroyed and the junket will not set. If it is still cold or hot from heating, setting is slow or uneven. Mix it in gently and leave the dish undisturbed while it sets.

Swap the cocoa

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

  4. Peanutfits less well

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