To Make a Sack Posset

Ingredients

Directions

Make the posset

  1. Grate the Naples biscuits into a pint of cream.

  2. Add the stick of cinnamon and heat over a slow fire.

  3. Boil until it thickens, then add the sack, lemon slice, and sugar.

  4. Stir gently over the fire without boiling to prevent curdling.

Serve

  1. Serve with dry toast.

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

What each ingredient does

Cream
Provides the rich body and fat that thicken into a smooth, set custard.
Naples biscuits
Add sweetness and flavour, and their crumbs give the cream extra body.
Sack
Adds a fortified-wine flavour and aroma that cuts through the richness.
Lemon
Its acidity helps the cream thicken and gives a bright, sharp balance.
Sugar
Adds sweetness to balance the acidity and the wine.

The step that matters

Stir gently without boiling. Cream that boils hard or heats too fast can split and curdle, leaving a grainy texture. Gentle, steady heat keeps the posset smooth as it thickens.

Swap the lemon
