Ingredients
Directions
Make the custard base
Crush the Boston cracker or soda biscuit into crumbs.
In a saucepan, combine the crumbs with 1 pint of cold milk.

Remove from heat immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the milk as it heats, giving the posset a smooth, custard-like body.
- Milk
- Forms the liquid base that the egg thickens into a creamy custard.
- Wine
- Adds acidity and flavour that cuts through the richness of the milk and egg.
- Boston cracker or soda biscuit
- Crumbs soak up liquid and add body and a light, toasty grain to the custard.
The step that matters
Stir the egg mixture into the simmering milk, stirring constantly, then remove from heat immediately.. Egg proteins set when heated, so adding them while stirring keeps them evenly dispersed. Overheating or letting it sit too long can curdle the egg and leave a grainy texture instead of a smooth custard.
Swap the nutmeg
How well each one fits the dish's main ingredients (biscuit, milk, egg, wine, sugar):
- Cinnamonfits better
- Nutmegthe original
- Capersfits less well
- Tarragonfits less well
Fit is the average pairing score against biscuit, milk, egg, wine, sugar. Candidates are from the same food group and used in at least 100 recipes.
