Save This classic British dessert achieves its velvety texture through the simple chemistry of cream and citrus. The acid from fresh lemon juice reacts with heated cream and sugar, creating a silky set without gelatin or eggs. Ready in minutes with just three ingredients, this elegant treat needs at least three hours to chill and achieve its signature pudding-like consistency.
The first time I encountered lemon posset was at a tiny London bistro where the waiter described it as just three ingredients. I laughed, thinking surely he was leaving something out, but that silky bowl of absolute sunshine changed my understanding of what dessert could be. Now it's my go-to when I need something that feels like pure magic but requires almost no effort.
I made these for my sister's summer birthday last year, setting them in mismatched vintage glasses I'd collected from thrift stores. Watching everyone's faces when they took that first spoonful of what looked like ordinary cream but tasted like the most luxurious lemon curd they'd ever had.
Ingredients
- Heavy cream: Use the highest fat content you can find since this is the entire structure of the dessert
- Granulated sugar: Regular white sugar dissolves perfectly and creates the right sweetness balance
- Fresh lemon juice: Absolutely must be fresh, never bottled, for that clean bright flavor
- Lemon zest: Grate this right into the mixture to capture all those fragrant citrus oils
Instructions
- Heat the cream and sugar:
- Combine in a medium saucepan over medium heat, stirring gently until sugar dissolves and cream just begins to simmer. Watch closely and do not let it boil.
- Add the lemon magic:
- Remove from heat and stir in the lemon juice and zest. Watch in wonder as the mixture instantly thickens.
- Cool briefly:
- Let the mixture sit for about 10 minutes to cool slightly while you get your serving glasses ready.
- Portion and chill:
- Pour evenly into 4 glasses or ramekins and refrigerate for at least 3 hours until set with a silky, pudding-like texture.
- Serve with love:
- Enjoy chilled, perhaps with fresh berries or a shortbread cookie on the side.
Save There's something deeply satisfying about a dessert that looks so understated in the glass but delivers such an incredible texture and flavor combination. Every time I serve these, someone asks for the recipe, and they never believe how simple it actually is.
Choosing Your Serving Vessels
I've learned that clear glasses show off the beautiful pale yellow color perfectly. Wine glasses, vintage tea cups, or simple ramekins all work beautifully depending on the mood you're creating.
Getting The Zest Right
A microplane grater gives you the finest zest without any bitter white pith. Zest your lemons before juicing them, and grate directly over your cooling mixture to catch every drop of those precious citrus oils.
Serving Suggestions
A few fresh raspberries or a thin shortbread cookie alongside each posset makes it feel complete. The tart berries and buttery cookie create this perfect little dessert trio that hits every note.
- Try topping with a dollop of whipped cream for extra richness
- A mint leaf adds lovely color contrast without competing flavors
- These pair beautifully with a glass of prosecco or muscat

Recipe Questions & Answers

Ensure you bring the cream just to a simmer without boiling, and measure ingredients precisely. The acid-to-cream ratio is crucial for proper setting. Also verify you're using heavy/double cream with adequate fat content.
