What Is Lemon Posset?
Lemon posset is a traditional British dessert that’s surprisingly simple — made from cream, sugar, and lemon juice. The acidity from the lemon naturally thickens the sweetened cream, resulting in a smooth, mousse-like texture without the need for eggs or gelatin.
Originally dating back to medieval times (when posset was a warm drink made with curdled milk and wine), today’s version is chilled, creamy, and bursting with bright citrus flavor. It’s perfect for when you want something quick, refreshing, and effortlessly elegant.

Ingredients You’ll Need
For the Posset
- 2 cups (480 ml) heavy cream or double cream
- ¾ cup (150 g) granulated sugar
- 1 large lemon, zested
- ¼ cup (60 ml) fresh lemon juice (about 1–2 lemons)
Optional Garnishes
- Fresh berries (raspberries, blueberries, or strawberries)
- Crushed shortbread or digestive biscuits
- Whipped cream
- Mint leaves
Tip: Use fresh lemon juice — bottled versions can taste bitter and won’t thicken as well.
Step-by-Step: How to Make Creamy Lemon Posset
Step 1: Heat the Cream and Sugar
In a medium saucepan, pour the heavy cream and sugar. Heat gently over medium heat, stirring occasionally until the sugar completely dissolves. Bring the mixture just to a gentle boil — not a rapid one.
Once it starts to bubble, let it simmer for 3 minutes, stirring occasionally. This step ensures the cream thickens slightly and the sugar caramelizes just enough to enhance the flavor.
Step 2: Add Lemon Juice and Zest
Remove the pan from the heat and stir in the lemon juice and zest. You’ll notice the mixture begins to thicken almost immediately as the acid reacts with the cream — that’s the natural magic of lemon posset!
Step 3: Strain and Pour
For the silkiest texture, strain the mixture through a fine sieve into a bowl or jug. This removes any bits of zest or undissolved sugar. Then, pour the smooth lemon cream into small serving glasses, ramekins, or jars.
Step 4: Chill to Perfection
Cover and refrigerate for at least 4 hours (or overnight) until set. The texture should be firm yet creamy, similar to panna cotta but without gelatin.
Step 5: Serve and Enjoy
Before serving, garnish with fresh berries, crushed biscuits, or a sprig of mint for a refreshing touch.
Expert Tips for the Perfect Lemon Posset
Get the Cream Right
Use heavy cream with at least 35% fat content. Lower-fat creams won’t set properly, resulting in a runny texture.
Adjust Sweetness and Tartness
If you like your desserts extra tangy, add an extra tablespoon of lemon juice. For a milder version, use less zest.
Avoid Overboiling
Boiling the cream too long can cause separation or a grainy texture. Stick to 3 minutes of gentle bubbling for a smooth, luscious finish.

2. Lavender Lemon Posset

3. Coconut Lemon Posset (Dairy-Free)

4. Mini Lemon Tartlets (No Bake!)
Pour set lemon posset into ready-made tart shells or biscuit bases for bite-sized desserts that look straight out of a bakery.
Troubleshooting: Why Didn’t My Lemon Posset Set?
Even though this recipe is simple, a few small missteps can prevent your posset from setting perfectly. Here’s how to fix them:
❌ Problem: Too Runny
Cause: Cream didn’t boil long enough or had too little fat.
Fix: Next time, simmer for the full 3 minutes and use full-fat heavy cream.
❌ Problem: Curdled Texture
Cause: Added lemon juice while the mixture was too hot.
Fix: Allow the cream to cool for 2–3 minutes before adding lemon juice.
❌ Problem: Grainy or Lumpy
Cause: Overboiled or heated too aggressively.
Fix: Maintain gentle heat and stir occasionally for even texture.
Pro Tip: If your posset still doesn’t set, don’t toss it! Use it as a lemon sauce over cakes, pancakes, or yogurt — it’s still delicious.
Serving Ideas and Pairings
- With shortbread cookies: The buttery crunch perfectly balances the creamy lemon flavor.

Storing and Make-Ahead Tips
- Refrigeration: Store covered in the fridge for up to 3 days.
- Freezing: Not recommended — freezing can cause separation.
- Make-Ahead: Prepare a day before serving; the flavor deepens beautifully overnight.
For best texture, chill your serving glasses before pouring the mixture — it sets faster and more evenly.
