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

What each ingredient does

Naples biscuits
Soak up milk and sack, thickening the posset and giving it a soft, bready body.
New milk
Forms the creamy base that the biscuits thicken and the sack is stirred into.
Sack
Adds alcohol flavour and aroma, and its acidity helps the milk curdle into a set, custard-like texture.
Sugar
Sweetens the posset, balancing the sharpness of the sack.

The step that matters

Pour in the sack while stirring continuously. Adding acidic sack to hot milk can cause curdling in lumps. Constant stirring disperses it evenly so the posset stays smooth and uniformly set.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Capersfits less well
  4. Gingerfits less well

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