Key Ingredients
- Heavy Cream - This is what gives posset its signature rich, velvety texture.
- Lemon Juice - Fresh lemon juice is essential because the acidity helps the dessert set naturally.
- Lemon Zest - Adds bold citrus aroma and flavor. If you love citrus spreads, try this Lime Curd Recipe.
- Sugar - Balances the tartness and sweetens the cream perfectly.
Step By Step Instructions
Step1: In a small saucepan, heat the cream and sugar, stirring until the sugar dissolves. Bring it to a boil, then adjust the heat so it doesn’t boil over and keep it at a medium boil for 5 minutes. (Over-boiling will cause a burnt taste)
Step2: Remove the pan from the heat and stir in the strained lemon juice and lemon zest, then set aside to cool for 15 minutes.
Step3: Take the mixture and divide it between 6 ramekins. Fill your serving cups about ¾” full so it sets up properly. (don’t have a ramekin, use 6 small glasses)
Step4: Place filled ramekins in the refrigerator for at least 2 hours or until fully set, then top with whipped cream if desired, along with a lemon slice, mint, or fresh berries.
How to Get Best Texture
- Use full-fat heavy cream
- Boil for the full 5 minutes
- Use fresh lemon juice
- Strain the juice to remove pulp
- Chill completely before serving
- Don’t overfill serving cups
Common Mistakes to Avoid
- Using half-and-half instead of heavy cream
- Skipping the boil time
- Using bottled lemon juice
- Over-boiling and scorching the cream
- Serving before fully set
- Adding too much liquid from fruit toppings
Variations
- Berry Lemon Posset: Top with fresh raspberries or blueberries
- Vanilla Lemon Posset: Add a splash of vanilla extract
- Orange Posset: Swap lemon juice for orange juice for a sweeter flavor
- Herbal Twist: Garnish with basil or thyme
- Coconut Version: Use coconut cream for a dairy-free experiment (texture may vary)

Expert Tips
- Use HEAVY cream. A lighter cream won’t have the fat content to set up properly. Heavy cream (≥ 36% fat) is essential for setting.
- Use real lemon juice, not concentrate.
- Strain your lemon juice to remove pulp and seeds for the smoothest finish.
- Don’t reduce the cream quantity — the ratio is key for proper setting.
- Let the mixture cool slightly before pouring to prevent condensation in your cups.
- For extra elegance, serve in clear glasses to show off that silky texture.
