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

What each ingredient does

Eggs
Set and thicken the posset as they cook, giving it a custard-like body.
Milk
Forms the creamy base that the eggs thicken into a smooth custard.
Sugar
Dissolves into the wine to sweeten the posset.
Sack
Adds wine flavour and acidity that balances the sweetness and richness.

The step that matters

Cook over low heat until thickened, stirring constantly. Egg proteins set at moderate temperatures, and too much heat or stopping the stirring can scramble the eggs into curds instead of a smooth, thickened custard.

Swap the nutmeg

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

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

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