Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that thickens and gives the posset its creamy body.
- Penny loaf
- Bread thickens the liquid as it softens and absorbs milk, giving body to the posset.
- Egg yolk
- Enriches the mixture and helps it set into a custard-like texture when heated.
- Butter
- Adds fat for richness and a smoother mouthfeel.
- Ale
- Adds a malty, slightly bitter flavour and acidity that cuts the richness.
The step that matters
Stir in the hot ale and boil everything together. Egg yolk thickens when heated, but if the mixture boils too hard or too long it can curdle and turn grainy. Stirring constantly while it heats keeps the texture smooth and even.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, egg, butter, sugar):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Parsleyfits less well
Fit is the average pairing score against milk, egg, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
