What Is Lemon Posset?

 

A lemon posset is a traditional British dessert made from just a few ingredients: cream, sugar, and lemon. What truly sets it apart from other creamy desserts like panna cotta is that it sets naturally without gelatin or eggs. The acid in the lemon interacts with the cream, creating a luxuriously smooth, tangy finish.

This version — inspired by Mary Berry’s beloved classic — hits that perfect balance between sweet and citrus, making it ideal for dinner parties, holidays, or just a simple summer treat.

Ingredients for Mary Berry Lemon Posset Easy Recipe

 

Here’s everything you’ll need to make this simple Mary Berry posset:

• Double cream – The backbone of this dessert; the higher fat content gives it richness and body.
• Caster sugar – Dissolves cleanly into the cream without grit.
• Fresh lemons – Juice and zest for bright citrus flavor.
• Optional garnishes: lemon zest, fresh berries, mint, or shortbread.

Ingredient Insights

 

Double cream dessert texture is crucial. Too thin, and the posset will be runny; too thick, and it can feel heavy. Mary Berry’s version gets this just right.

Using fresh lemon juice instead of bottled juice keeps the acidity bright and natural — and that acidity is what helps the posset set.

Step-by-Step: How to Make Lemon Posset

 

This is where the magic happens. Follow these steps for an effortless, delicious result:

1. Heat the Cream and Sugar

 

In a heavy-bottomed saucepan, combine the cream and sugar over medium heat. Stir gently until the sugar is fully dissolved — this prevents grainy texture.

Tip: Do not let it boil vigorously. A gentle simmer is all you need.

2. Simmer to Infuse

 

Once the sugar has dissolved, let the mixture simmer for a few minutes. This slightly reduces the cream, intensifying the flavor without overcooking.

3. Add Lemon Juice and Zest

 

Remove from heat and stir in the freshly squeezed lemon juice and zest. The acidity causes the cream to thicken naturally.

4. Strain for Smooth Texture

 

For an ultra-silky finish, strain the mixture through a fine sieve into a bowl.

5. Chill Until Set

 

Divide into serving glasses and refrigerate for at least 3 hours or overnight.

Pro tip: Use a chilled tray to speed up the cooling process.

Why Your Posset Might Not Set

 

Even experienced cooks hit snags. Here are common reasons:

• Lemon juice too weak: Not enough acidity to thicken the cream.
• Too much cream relative to acid: Throws off the balance.
• Skipping the simmer: Shortens the emulsion process.

If your posset is too soft, let it chill longer — sometimes a little more time is all it needs.

Serving & Presentation Ideas

 

A dessert this elegant deserves an equally beautiful presentation:

• Serve in small glasses or ramekins for a refined look.
• Garnish with lemon zest curls and a sprig of mint.
• Add fresh raspberries or blueberries for color and contrast.
• Pair with shortbread biscuits for extra texture.
