3-Ingredient Lemon Posset

This 3-Ingredient Lemon Posset is a velvety, tangy lemon dessert that comes together in minutes with just cream, sugar, and fresh lemons, delivering a bright, creamy finish you won’t believe took only three ingredients. Silky cream infused with zesty lemon brightens each spoonful, creating a luscious, lightly sweet custard that melts on the tongue. Ready in a snap and chilled to a pillowy dream, it’s the perfect make-ahead citrus dessert your friends will rave about.

Key Ingredients

Here’s what you need to pull off this simple yet elegant posset:

• 2 cups heavy cream: Rich base that gives the posset its silky, custard-like texture.
• 1/2 cup granulated sugar: Sweetens the cream and helps it thicken as it simmers.
• 2 lemons zested and juiced: Fresh zest and juice add bright acidity and help the cream set.

How To Make 3-Ingredient Lemon Posset

Making this dessert is almost too easy, but there are a few key moments—like gently simmering the cream and fully incorporating the lemon—that ensure a perfect set and vibrant tang. Follow these detailed steps to transform just three pantry staples into a show-stopping, refreshingly tart custard that’s ready in minutes, then patiently chills into a silky treat.

1. In a saucepan combine heavy cream and sugar. Measure out 2 cups of heavy cream and 1/2 cup of granulated sugar, then stir gently in a medium saucepan until the sugar begins to dissolve.

2. Heat over medium heat, stirring until sugar dissolves and mixture is hot but not boiling. Keep the flame at medium, stirring with a wooden spoon or whisk so the mixture reaches about 180°F without bubbling.

3. Bring to a gentle simmer for 3 minutes, stirring occasionally. Let the sweetened cream simmer just long enough to concentrate and thicken—watch carefully so it doesn’t boil over.

4. Remove from heat and stir in lemon juice and zest. Immediately whisk in the juice and finely grated zest of 2 lemons for peak brightness and natural setting.

5. Strain mixture through a fine mesh sieve into serving glasses. This removes any zest bits or foam, leaving you with a smooth, velvety custard.

6. Refrigerate for at least 4 hours until set. Chill the glasses uncovered or loosely covered so the posset firms up into a pillowy, tangy delight.

Serving Suggestions

This posset is a versatile canvas for sweet and fresh pairings—perfect for summertime or any citrus craving.

• Top with fresh berries like raspberries or blueberries for a pop of color and sweet-tart balance.
• Garnish each glass with a sprig of fresh mint to add a cool, herbal contrast.
• Serve alongside crisp shortbread cookies or buttery biscotti for a delightful textural crunch.
• Offer a small spoonful of berry compote or drizzle of honey for extra sweetness and a pretty presentation.

Tips For Perfect 3-Ingredient Lemon Posset

Even though this recipe is foolproof, these tips will make sure your posset is absolutely stellar every time.

• Use ripe, aromatic lemons for best flavor. Fresh, thin-skinned lemons pack more zest oils and juice, boosting that citrus punch.
• Double or triple the recipe for larger batches. Just keep your saucepan size in mind to avoid spills while simmering.
• Posset will firm up more the longer it chills. If you find it too soft after 4 hours, give it an extra hour or two in the fridge.
• Serve with fresh berries or mint for garnish. A vibrant topping not only looks gorgeous but complements the tangy custard perfectly.

How To Store It

Proper storage keeps your lemon posset fresh and flavorful for days, so you can enjoy it at your own pace or prep well ahead for gatherings.

• Refrigerator: Cover each serving glass tightly with plastic wrap or a lid and store for up to 3 days.
• Airtight container: If you’ve made it in a larger dish, transfer to an airtight container to prevent fridge odors from seeping in.
• Freeze in portions: For longer storage (up to 1 month), transfer firm posset into freezer-safe ramekins, cover, and thaw overnight in the fridge before serving.
• Label and date: Always mark your containers with the date you prepared the posset to keep track of freshness.

Frequently Asked Questions

Here are quick answers to common questions about 3-Ingredient Lemon Posset:

• Q: How long does it take to prepare and chill this 3-Ingredient Lemon Posset?

It takes about 8 minutes to prepare and cook the mixture (including dissolving sugar and simmering for 3 minutes), then requires at least 4 hours of refrigeration to set, so plan for around 4 hours and 8 minutes in total.

• Q: How many servings does this recipe yield?

This recipe yields approximately four 4-ounce servings when divided into small dessert glasses; you can adjust portion sizes or glassware to serve up to six smaller portions.

• Q: What should I do if my posset doesn’t set firmly?

Ensure you simmer the cream and sugar for the full 3 minutes without boiling over, as this concentrates the mixture for proper setting. Also verify that your refrigerator is at a cold temperature and that you’ve chilled the posset for at least 4 hours.

• Q: Can I use other types of citrus or sweeteners?

Lemons provide the right balance of acidity to coagulate the cream; substituting with limes or oranges will alter the flavor and may affect the set. Granulated sugar is recommended for proper texture; liquid sweeteners like honey or maple syrup may change consistency.

• Q: Is it possible to prepare this dessert ahead of time?

Yes, you can prepare the posset up to two days in advance. After straining into serving glasses and chilling until set, cover the glasses tightly and keep them refrigerated until serving.

Top each serving with fresh berries such as raspberries or blueberries, add a few mint leaves, or finish with extra lemon zest for brightness and visual appeal.

• Q: Can I double or triple this recipe for larger gatherings?

Absolutely. Multiply each ingredient by your desired amount, use a larger saucepan to prevent overflow, maintain the same heating and simmering times, then strain into more serving glasses and chill as instructed.
