Ingredients You’ll Need
Nothing complicated here—just a few simple ingredients that come together to make magic. Each one plays an essential role: the heavy cream gives it that luscious, velvety texture; the sugar balances the tartness with gentle sweetness; the freshly squeezed lemon juice provides a vibrant, zesty punch; and lemon zest adds a fresh aromatic boost that brightens every spoonful.
- 2 cups heavy cream: This forms the rich, creamy base that makes the posset so decadent and smooth.
- 3/4 cup granulated sugar: Sweetens the dessert just enough to complement the sharpness of the lemons.
- 1/3 cup freshly squeezed lemon juice: Adds that fresh, tangy burst that defines this dish.
- 1 tablespoon lemon zest: Injects a lively citrus fragrance and depth to the flavor profile.
How to Make Lemon Posset Recipe
Step 1: Combine the Cream and Sugar
Start by pouring the heavy cream and granulated sugar into a medium saucepan. Heat it over medium heat, stirring constantly to make sure the sugar dissolves completely and you don’t end up with any grainy bits. Your goal is a smooth, velvety mixture that’s gently coming to a boil.
Step 2: Simmer the Mixture
Once the cream mixture reaches a gentle boil, reduce the heat slightly and let it simmer for 3 minutes while stirring continuously. This step is key for thickening the cream and infusing the taste with sweetness that perfectly complements the lemon’s acidity.
Step 3: Add the Lemon
Remove the saucepan from the heat and stir in the freshly squeezed lemon juice and lemon zest. The heat from the cream will gently “cook” the lemon juice, giving the posset its signature silky texture and bright flavor.
Step 4: Let It Sit and Strain for Smoothness
Allow the mixture to rest for about 5 minutes to let the zest infuse fully, then strain it through a fine mesh sieve into a bowl or pitcher. This ensures your posset is perfectly smooth and free from any zest bits, elevating that luxurious mouthfeel you’re aiming for.
Step 5: Chill Until Set
Pour the strained mixture evenly into ramekins or small serving glasses. Pop them in the fridge and let the posset chill for a minimum of 4 hours. Patience here pays off—the posset sets to a delicate, creamy pudding consistency that’s pure bliss.
How to Serve Lemon Posset Recipe

Garnishes
Simple garnishes can take your Lemon Posset Recipe to the next level. Fresh berries like raspberries, blueberries, or strawberries make a colorful, juicy contrast. A light dusting of finely grated lemon zest or a little twist of lemon peel adds elegance and extra zing. For an indulgent touch, a small dollop of softly whipped cream is perfect.
Side Dishes
This posset pairs wonderfully with light, buttery shortbread cookies or crisp biscotti to give your dessert a complementary crunchy texture. Fresh fruit also works beautifully alongside, especially when in season—think juicy berries or stone fruits that boost freshness and balance richness.
Creative Ways to Present
Elevate your presentation by layering the posset with a fruit compote or a drizzle of tangy fruit coulis. Serve it in petite glasses garnished with edible flowers for a special occasion. Even setting the posset in small jars with a ribbon around the lid makes a charming gift or elegant party favor.
Make Ahead and Storage
Storing Leftovers
If you have any posset left over, keep it covered tightly in the refrigerator. It will maintain its silky texture and fresh lemon flavor for up to 3 days, making it a perfect make-ahead dessert for busy days or last-minute guests.
Freezing
Because of its delicate creamy texture, freezing lemon posset is not generally recommended. Freezing can cause the texture to become grainy or separate once thawed. It’s best enjoyed fresh or refrigerated.
Reheating
This dessert is meant to be served chilled, so reheating is not necessary or advised. Its charm lies in its cool, creamy texture that delightfully cools you down and refreshes your palate.
FAQs
Can I use bottled lemon juice instead of fresh?
Freshly squeezed lemon juice is key to getting that vibrant, natural flavor and aroma. Bottled lemon juice tends to be more acidic and less fresh, which can affect the taste and texture, so fresh is definitely best for this Lemon Posset Recipe.
Is there a substitute for heavy cream?
Heavy cream is essential for the rich texture of lemon posset. Using alternatives like half-and-half or milk will not give the dessert the same creamy thickness and luxurious mouthfeel.
How long does the posset take to set?
You should chill the posset for at least 4 hours in the refrigerator. This allows the creamy mixture to fully thicken and set to the perfect pudding consistency.
Can I make this lemon posset vegan?
This classic recipe is dairy-based, but you could experiment with full-fat coconut cream and adjust the sweetness accordingly to create a vegan version. Keep in mind the texture and flavor will be a bit different.
What can I do if my posset is too tart?
If you find the posset too tangy for your taste, consider reducing the lemon juice slightly or increasing the sugar in future batches. Serving it with a sweet berry compote or whipped cream can help balance the tartness.
