Lemon Posset is one of the simplest yet most luxurious desserts ever created. With just three main ingredients — cream, sugar, and lemon — it transforms into a silky, tangy, and perfectly balanced treat that feels both refreshing and indulgent. This classic British dessert dates back centuries, originally served as a warm drink before evolving into the creamy, chilled delight we know today. Its smooth texture, bright citrus flavor, and effortless preparation make it a favorite for dinner parties, holidays, or any time a touch of elegance is needed.
The Essence of Lemon Posset
Lemon Posset is a dessert that embodies the beauty of simplicity. It’s made by gently simmering cream and sugar, then adding lemon juice, which naturally thickens the mixture without the need for eggs or gelatin. The acid from the lemon reacts with the cream, creating a smooth, custard-like texture that sets beautifully once chilled. The result is a dessert that’s rich yet light, sweet yet tart, and utterly irresistible. Its creamy consistency and vibrant lemon flavor make it a perfect ending to any meal.
Why Choose Lemon Posset?
Lemon Posset is the perfect dessert for those who appreciate elegance without complication. It requires minimal ingredients, no baking, and only a few minutes of active preparation. Despite its simplicity, it delivers a flavor and texture that rival the most sophisticated desserts. It’s also incredibly versatile — you can serve it plain, with fruit, or topped with shortbread or whipped cream. Its bright, citrusy flavor makes it ideal for spring and summer, while its creamy richness makes it comforting year-round.
The Science of a Perfect Lemon Posset
The magic of Lemon Posset lies in the chemistry between cream and lemon juice. When lemon juice is added to hot cream, the acid causes the proteins in the cream to coagulate slightly, thickening the mixture as it cools. The sugar balances the acidity, creating a smooth, velvety texture. The key is to use the right ratio of ingredients and to heat the cream gently — too much heat can cause curdling, while too little can prevent proper thickening. The result, when done correctly, is a dessert that’s perfectly set, creamy, and bursting with lemon flavor.
Choosing the Best Ingredients
- Cream: Use heavy cream or double cream with at least 35% fat for the best texture. Lower-fat creams won’t set properly.
- Sugar: Granulated sugar dissolves easily and balances the tartness of the lemon.
- Lemons: Fresh lemons are essential. Use both the juice and zest for maximum flavor.
- Vanilla (optional): Adds warmth and depth to the flavor.
- Toppings: Fresh berries, mint leaves, or shortbread cookies complement the creamy lemon base beautifully.
Step-by-Step Recipe: Classic Lemon Posset
Ingredients
- 2 cups (480 ml) heavy cream
- ¾ cup (150 g) granulated sugar
- 3 tablespoons fresh lemon juice
- 1 teaspoon finely grated lemon zest
- Optional: ½ teaspoon vanilla extract
Instructions
- Heat the cream and sugar: In a medium saucepan, combine the cream and sugar. Place over medium heat and bring to a gentle simmer, stirring occasionally to dissolve the sugar. Once it begins to bubble, reduce the heat slightly and let it simmer for 3 minutes. Do not let it boil vigorously.
- Add the lemon: Remove the saucepan from the heat and stir in the lemon juice, zest, and vanilla (if using). The mixture will begin to thicken slightly as the acid reacts with the cream.
- Cool and strain: Let the mixture cool for 10 minutes, then strain it through a fine sieve to remove the zest and any lumps. This ensures a silky-smooth texture.
- Pour and chill: Pour the mixture into serving glasses or ramekins. Refrigerate for at least 4 hours, or until set. The posset should be firm enough to hold its shape but still creamy and spoonable.
- Serve: Garnish with fresh berries, mint leaves, or a dusting of lemon zest before serving.
Tips for Perfect Lemon Posset
- Use fresh lemons: Bottled lemon juice lacks the brightness and aroma of fresh juice.
- Don’t overheat the cream: Boiling can cause separation. A gentle simmer is all that’s needed.
- Strain the mixture: Ensures a smooth, velvety texture.
- Chill thoroughly: The posset needs several hours to set properly.
- Adjust sweetness: Taste before chilling and add more sugar if desired.
- Serve cold: Lemon Posset is best enjoyed chilled for maximum creaminess and flavor.
