Mary Berry’s Lemon Posset is a classic creamy dessert made by gently heating double cream with sugar, then adding fresh lemon juice to thicken it naturally. As it cools, the acidity from the lemon sets the cream into a velvety, pudding-like texture without the need for eggs or gelatine. It’s traditionally served chilled in small cups or glasses, often with shortbread biscuits or fresh berries.

Ingredients

Scale

  • 600ml double cream

  • 150g caster sugar

  • 2 large lemons (zest and juice)

  • Fresh berries, for serving (optional)

  • Shortbread biscuits, for serving (optional)

Instructions

Step 1: Heat the Cream and Sugar

Pour the double cream into a medium saucepan and add the caster sugar. Gently heat over medium-low heat until it reaches a light simmer. Stir occasionally to dissolve the sugar completely. Do not let it boil vigorously, as this may affect the smooth texture.

Step 2: Simmer Briefly

Once the cream mixture begins to bubble lightly around the edges, let it simmer gently for about 2–3 minutes. This helps thicken the cream slightly and develops a richer flavor.

Step 3: Add the Lemon

Remove the pan from the heat. Add the finely grated lemon zest and freshly squeezed lemon juice. Stir well to combine. The lemon juice will immediately begin to thicken the cream through natural chemical reaction. Taste and adjust with a little more zest for extra brightness if you like.

Step 4: Strain for Smoothness (Optional)

If you prefer a perfectly silky finish, strain the mixture through a sieve into a jug to remove the zest. Otherwise, leave the zest in for added flavor and texture.

Step 5: Pour Into Serving Glasses

Divide the lemon cream mixture evenly among your serving glasses or ramekins. Leave some space at the top for garnishing later.

Step 6: Chill Until Set

Place the possets in the fridge for at least 3–4 hours, or until fully set. They should have a soft, creamy texture similar to a smooth custard.

Step 7: Garnish and Serve

Just before serving, top with fresh raspberries, strawberries, or a light sprinkle of lemon zest. Add a shortbread biscuit on the side for a lovely crunch.
