A Brief History of Lemon Posset
Lemon posset dates back to the Middle Ages when it was initially a warm drink of milk curdled with wine or ale.

Ingredients for Mary Berry Lemon Posset Recipe
To make this divine dessert, you’ll need the following:
- 600ml double cream
- 200g caster sugar
- 2 lemons (zested and juiced)
- Lemon zest for garnish (optional)
- Fresh berries or mint leaves (optional for serving)
Step-by-Step Instructions

Follow these easy steps to whip up the perfect Mary Berry Lemon Posset Recipe:
Step 1: Heat the Cream and Sugar
In a medium saucepan, pour the double cream and add the caster sugar. Stir well and bring the mixture to a gentle boil over medium heat. Let it boil for about 3 minutes while stirring occasionally.
Step 2: Add the Lemon Juice and Zest
Remove the saucepan from heat. Add in the freshly squeezed lemon juice and zest. Stir until well combined. The citrus will help set the cream naturally without gelatin.
Step 3: Strain the Mixture (Optional)
If you prefer a smoother texture, strain the mixture through a fine sieve to remove any zest or lumps.
Step 4: Pour and Chill
Carefully pour the posset into small ramekins or serving glasses. Let them cool to room temperature before transferring to the refrigerator. Chill for at least 4 hours, or overnight for best results.
Step 5: Garnish and Serve
Before serving, garnish with extra lemon zest, fresh berries, or mint leaves. Serve chilled and enjoy the creamy, citrusy delight.
