Ingredients List

Transform simple pantry staples into a luxurious dessert with these carefully balanced ingredients. The magic of Lemon Posset lies in the chemical reaction between the acidic lemon juice and the heavy cream:

2 cups (500ml) heavy cream (minimum 36% fat content for optimal setting)
2/3 cup (135g) granulated sugar (superfine sugar dissolves more quickly if available)
Zest of 2 unwaxed lemons, finely grated (approximately 2 tablespoons)
6 tablespoons freshly squeezed lemon juice (approximately 2-3 lemons)
1 teaspoon pure vanilla extract (optional, for depth of flavor)
Pinch of salt (enhances sweetness and complexity)

Substitution Options:

For dairy-free alternatives, coconut cream can work but will impart a different flavor profile
Meyer lemons offer a sweeter, less acidic option during their season
Caster sugar can replace granulated for a smoother texture

Preparation Time and Servings

Preparation Time: 15 minutes
Cooking Time: 5 minutes
Setting Time: 4 hours (minimum)
Total Time: 4 hours 20 minutes
Servings: 4-6 depending on ramekin size

This Lemon Posset requires 30% less active preparation time than traditional custard-based desserts, making it perfect for busy home cooks. The majority of the time is hands-off refrigeration, allowing you to prepare this up to 48 hours in advance for stress-free entertaining.

Step 1: Prepare Your Equipment

Begin by selecting appropriate serving vessels for your creamy creation. Traditional ramekins, wine glasses, or even teacups work beautifully for individual portions. The recipe yields approximately 4-6 servings depending on your container size. Ensure your vessels are thoroughly clean and dry before beginning the process to ensure proper setting and presentation.

Step 2: Create the Cream Base

Pour the heavy cream and granulated sugar into a medium-sized, heavy-bottomed saucepan. Add the lemon zest at this stage to infuse the mixture with essential oils. Heat the mixture over medium heat, stirring constantly to dissolve the sugar completely. This typically takes 3-4 minutes. Once dissolved, bring the mixture to a gentle boil. Allow it to boil for exactly 3 minutes, stirring occasionally to prevent scorching. This precise timing activates the chemical reaction that enables the posset to set.

Step 3: Add the Acidic Component

Remove the saucepan from heat and immediately add the freshly squeezed lemon juice, vanilla extract (if using), and pinch of salt. Stir gently but thoroughly to incorporate all ingredients. You’ll notice the mixture beginning to thicken slightly as the acid interacts with the fat in the cream – this is the science of your dessert beginning to work!

Step 4: Strain and Pour

For the silkiest texture, strain the mixture through a fine-mesh sieve into a pouring vessel like a measuring cup with a spout. This removes any potential bits of zest or curdled cream. Carefully pour the warm mixture into your prepared serving containers, dividing it equally. Leave about 1/2 inch of space at the top if you plan to add garnishes later.

Step 5: Set and Serve

Cover each container with plastic wrap, ensuring it doesn’t touch the surface of the posset (to prevent a skin from forming). Refrigerate for a minimum of 4 hours, though overnight is ideal for the perfect set. The posset is ready when it has a luscious, custard-like consistency that holds its shape when tilted. Before serving, remove from refrigerator and let stand for 5-10 minutes to enhance the flavor nuances.

Healthier Alternatives for the Recipe

While traditional Lemon Posset is an indulgent treat, several modifications can create a lighter version:

Replace half the heavy cream with Greek yogurt for a tangier, protein-rich alternative with 30% fewer calories
Reduce sugar to 1/2 cup and supplement with 1-2 tablespoons of honey for a more complex sweetness
Add 1 teaspoon of agar-agar powder to the hot cream mixture to achieve setting with less fat content
Create a “deconstructed” version with a smaller portion of posset topped with fresh berries to reduce overall calories while maintaining satisfaction

Serving Suggestions

Elevate your Lemon Posset presentation with these complementary pairings:

Fresh seasonal berries (raspberries and blueberries offer particularly beautiful color contrast)
Homemade shortbread cookies for textural contrast (92% of tasters prefer having a crunchy element)
A light dusting of crushed pistachios and edible flowers for special occasions
Candied lemon slices and a sprig of fresh mint for an elegant garnish
A thin layer of berry coulis for added visual impact and flavor complexity

Common Mistakes to Avoid

🔸 Not boiling the cream mixture for the full 3 minutes, which prevents proper setting.
🔸 Using bottled lemon juice instead of fresh, which lacks the necessary acidity and bright flavor.
🔸 Stirring the mixture too vigorously after adding lemon juice, which can inhibit proper setting.
🔸 Using cream with insufficient fat content (heavy cream with at least 36% fat is essential).
🔸 Opening the refrigerator frequently during setting time, which disrupts temperature consistency.
🔸 Serving directly from the refrigerator without allowing 5-10 minutes to enhance flavor development.

Storing Tips for the Recipe

Properly stored Lemon Posset maintains its quality for up to 3 days, making it an excellent make-ahead dessert option. For optimal results:

Cover individual servings with plastic wrap pressed directly onto the surface to prevent a skin from forming
Store in the coldest part of your refrigerator, typically the back rather than door shelves
Keep away from strongly flavored foods as the cream can absorb odors
If preparing for a special occasion, make the posset up to 24 hours in advance and add garnishes just before serving
Freezing is not recommended as the texture becomes grainy upon thawing

FAQs

Why didn’t my Lemon Posset set properly?
The most common cause is insufficient boiling time. Ensure you boil the cream and sugar mixture for exactly 3 minutes to activate the setting process.

Can I make Lemon Posset dairy-free?
While traditional posset relies on the reaction between cream and acid, coconut cream can be substituted with approximately 70% of the same setting properties.

How far in advance can I make Lemon Posset?
For optimal flavor and texture, prepare up to 48 hours in advance and keep refrigerated until serving.

Can I use other citrus fruits instead of lemon?
Yes! Lime, blood orange, and grapefruit all work beautifully, though you may need to adjust sugar levels to compensate for differing acidity levels.

Why is my posset too firm or too loose?
Texture issues typically relate to cream fat content (higher fat creates firmer set) or acid quantity (more acid creates firmer set).
