Ingredients
| Ingredient | Amount |
| Heavy whipping cream | 2 cups |
| Granulated sugar | â…” cup |
| Fresh lemon juice | â…“ cup |
| Fresh lemon zest | 1 tablespoon |
| Fresh mint leaves | For garnish |
| Lemon slices | For garnish |
Step-by-Step Instructions
1. Combine the Cream and Sugar
Pour the heavy whipping cream into a medium saucepan.
Add the granulated sugar and place the saucepan over medium heat.
Stir continuously until the sugar has completely dissolved and the cream reaches a gentle boil. This should take approximately 3–4 minutes.
2. Simmer the Mixture
Once the cream begins to boil, reduce the heat slightly.
Continue simmering for approximately 3 minutes, stirring constantly.
Keep a close eye on the saucepan so the cream doesn’t boil over.
The mixture should remain smooth and slightly thickened.
3. Add the Lemon
Remove the saucepan from the heat.
Immediately whisk in the fresh lemon juice and lemon zest.
The lemon juice reacts with the cream and causes the mixture to thicken naturally.
Continue whisking until everything is smooth and evenly combined.
4. Pour Into Serving Glasses
Carefully divide the lemon mixture between 4 small serving glasses, ramekins, or dessert jars.
If you want an especially smooth finished texture, you can strain the mixture through a fine-mesh sieve before pouring it into the glasses.
Allow the desserts to cool at room temperature for a short time.
5. Chill
Once the desserts have cooled, cover them and place them in the refrigerator.
Chill for at least 4 hours, or preferably overnight.
The posset should be completely chilled and set with a smooth, creamy consistency.
6. Garnish and Serve
Just before serving, garnish each portion with a thin lemon slice and a small fresh mint leaf.
Serve chilled and enjoy immediately.
Why You’ll Love This Recipe
This lemon posset is incredibly easy to prepare while still feeling elegant enough for a special occasion.
The combination of rich cream, sweet sugar, and fresh lemon creates a beautifully balanced dessert with a silky texture and bright citrus flavor.
There is no complicated custard-making process and no need for gelatin. The acidity of the lemon naturally helps the cream set as it chills.
Best Tips for Success
Use freshly squeezed lemon juice for the brightest and most natural flavor.
Fresh lemon zest adds an extra layer of citrus aroma, so don’t skip it.
Stir the cream and sugar continuously while heating to help the sugar dissolve evenly and prevent scorching.
Keep the heat moderate. The cream should reach a gentle boil rather than an aggressive boil.
Allow enough chilling time. Four hours is the minimum, while overnight refrigeration usually gives an especially firm and creamy texture.
Best Ingredient Options
Heavy whipping cream is essential for achieving the rich, silky texture that makes posset special.
Fresh lemons provide the best flavor. Choose lemons that feel firm and heavy for their size and have fragrant yellow skin.
For a slightly different citrus flavor, you can experiment with a small amount of lime or orange zest, although classic lemon provides the signature flavor.
Recipe Variations
For a berry version, serve the chilled posset with fresh strawberries, raspberries, or blueberries.
For a lemon-berry combination, add a spoonful of homemade berry compote over each portion just before serving.
For an extra elegant presentation, top each glass with whipped cream, a little lemon zest, and fresh berries.
For a slightly more aromatic dessert, add a small amount of finely grated orange zest along with the lemon zest.
What to Serve With It
Creamy Lemon Posset is delicious served with fresh berries and a few crisp cookies or shortbread biscuits.
A small piece of buttery shortbread makes an especially good accompaniment because its mild flavor balances the bright lemon.
For a dinner party, serve the posset in small glass jars or elegant dessert glasses for an attractive individual presentation.
Make-Ahead Instructions
This dessert is perfect for making ahead.
Prepare the posset the day before serving, cover the individual glasses, and refrigerate overnight.
Add the lemon slices and mint immediately before serving so the garnish stays fresh.
Storage
Keep the finished posset covered and refrigerated.
For the best texture and freshness, enjoy it within approximately 3 days.
Always keep the dessert refrigerated until ready to serve.
Reheating
Reheating is not recommended.
Lemon posset is designed to be served chilled, and warming it can affect its set texture.
Freezing
Freezing is not recommended because the cream-based texture may become grainy or separate after thawing.
For the smoothest result, prepare the dessert fresh and keep it refrigerated.
Common Mistakes to Avoid
Don’t use bottled lemon juice if you want the freshest flavor. Freshly squeezed lemon juice makes a noticeable difference.
Avoid boiling the cream too aggressively, as it can cause the mixture to boil over or develop an undesirable texture.
Don’t reduce the chilling time. The dessert needs several hours to fully set.
Avoid adding too much lemon juice. The balance between cream, sugar, and acidity is important for both texture and flavor.
Finally, don’t garnish too early. Add mint and lemon slices just before serving for the freshest presentation.

Frequently Asked Questions
