Ingredients for Lemon Posset (US Measurements)

• 16 oz heavy cream
• 2/3 cup sugar (about 4.7 oz)
• 6 tablespoons lemon juice + zest (from 1 large or 2 medium lemons)

🍋 Always use fresh lemon juice. Bottled won’t give the same vibrant flavor.

How to Make Lemon Posset Step-by-Step

1. Zest and Juice the Lemons

• Zest your lemon(s). Aim for 2 teaspoons of finely grated zest.
• Juice until you get 6 tablespoons of fresh juice.

2. Heat Cream and Sugar

• In a medium saucepan, combine cream and sugar.
• Heat over medium-high, stirring to dissolve the sugar.
• Bring to a gentle boil. Then reduce heat and boil for 8 minutes, stirring constantly.

⚠️ Watch the pot—it can bubble up quickly! Lower the heat if needed to avoid spillover.

3. Add Lemon and Cool

• Remove from heat.
• Stir in lemon juice and zest.
• Let the mixture sit for 10–15 minutes to cool and thicken slightly.

4. Strain and Divide

• Stir again, then strain through a fine mesh sieve to remove zest.
• Pour into 6 small ramekins or glasses.
• Cover with plastic wrap.

5. Chill Until Set

• Refrigerate for at least 1 hour, or overnight.
• Serve chilled.

🕒 I always make it the night before. It gives me one less thing to stress about when guests are coming over.

6. Garnish and Serve

Decorate with:

• Fresh raspberries or blueberries
• A small mint leaf
• A tiny twist of lemon zest

Flavor Variations to Try

• Orange Posset: Use orange juice and zest for a softer citrus flavor.
• Lime Posset: Sharp, tangy, and refreshing.
• Lemon Posset with Condensed Milk: Swap sugar and some cream for sweetened condensed milk for extra richness.
• Lemon Posset Brûlée: Once set, sprinkle with sugar and torch for a crisp topping.

FAQs: Your Lemon Posset Questions Answered

What is lemon posset made of?

Just three things: heavy cream, sugar, and lemon juice + zest.

How does lemon posset set without gelatin?

The acid in the lemon reacts with the cream and sets it naturally.

Can I make lemon posset ahead of time?

Absolutely! Make it up to 2 days ahead. Just cover and chill.

Can I use milk instead of cream?

No. It won’t set correctly. Stick with full-fat heavy cream.

Why didn’t my lemon posset set?

• Cream wasn’t boiled long enough
• Too little lemon juice
• Cream wasn’t fatty enough

Is lemon posset healthy?

It’s indulgent, yes. But you can reduce sugar or use less cream per serving.

Can I use brown sugar?

Yes, but it will change the color and add a caramel note. Still delicious!

Is this the same as panna cotta?

Not quite. Panna cotta uses gelatin; posset is all about lemon acid.

What to Serve with Lemon Posset

• Butter cookies or shortbread
• Almond biscotti
• Fresh berries or fruit compote

My Favorite Tips for Perfect Lemon Posset
