How to Serve Lemon Posset
With Fresh Berries: Raspberries or blueberries contrast the creamy tang beautifully.
Add Crunch: A biscotti, shortbread cookie, or gingersnap on the side is a dream.
In Elegant Glasses: Serve in shot glasses or small jars for a stylish touch at dinner parties.

Tips for Success
Use Fresh Lemon Juice: Bottled juice won’t provide the same flavor or acidity.
Don’t Overboil: Just simmer the cream for 3 minutes once it reaches a boil—don’t let it reduce too much.
Strain if Needed: To ensure your posset is silky smooth.
Let It Chill Fully: Give it at least 3 hours in the fridge to set properly.
