What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without the fuss. Most of these are pantry staples, and substitutions are easy if you need them.

• For the Lemon Posset:
  • Heavy cream, 2 cups (480 ml) – I prefer using Organic Valley cream for richness
  • Granulated sugar, 2/3 cup (135 g)
  • Fresh lemon juice, 1/4 cup (60 ml) – about 2 large lemons, freshly squeezed
  • Lemon zest, from 1 lemon (adds bright citrus flavor)
• For the Fresh Strawberry Coulis:
  • Fresh strawberries, 1 cup (150 g), hulled and quartered – use ripe, juicy berries for best flavor
  • Granulated sugar, 2 tablespoons (25 g) – adjust based on berry sweetness
  • Lemon juice, 1 teaspoon (5 ml) – adds a subtle tang to balance sweetness
• For the Easy Shortbread:
  • All-purpose flour, 1 cup (120 g)
  • Unsalted butter, 1/2 cup (113 g), softened – Land O’Lakes works great here
  • Powdered sugar, 1/3 cup (40 g)
  • Vanilla extract, 1 teaspoon (5 ml)
  • Salt, a pinch

Substitution tips: Use coconut cream instead of heavy cream for a dairy-free version. Almond flour can replace all-purpose flour for gluten-free shortbread, though the texture will be a bit different. Swap strawberries for raspberries or mixed berries in the coulis if you want a seasonal twist.

Equipment Needed

• Medium saucepan – essential for gently heating the cream mixture without scorching.
• Fine mesh sieve or strainer – to remove lemon zest bits and achieve a silky posset texture.
• Blender or food processor – to puree the strawberry coulis smoothly; a handheld immersion blender works fine too.
• Mixing bowls – for combining the shortbread dough and other ingredients.
• Baking sheet and parchment paper – for baking the shortbread evenly and preventing sticking.
• Measuring cups and spoons – accuracy in lemon juice and sugar is key for a balanced flavor.

If you don’t have a food processor, mashing the strawberries with a fork and pressing through a sieve will do the trick. For the shortbread, a simple wooden spoon and your hands work just fine if you don’t own a mixer.

Preparation Method

1. Prepare the Lemon Posset: In a medium saucepan, combine 2 cups (480 ml) of heavy cream and 2/3 cup (135 g) granulated sugar. Heat over medium heat, stirring occasionally, until the sugar dissolves and the mixture just starts to gently simmer (about 5-7 minutes). Avoid boiling vigorously to keep the cream from scorching.
2. Remove from heat and stir in 1/4 cup (60 ml) fresh lemon juice and the zest from one lemon. The mixture will thicken slightly as the acid interacts with the cream.
3. Pour the mixture through a fine mesh sieve into small serving glasses or ramekins to remove zest bits. Let cool for 10 minutes at room temperature, then refrigerate for at least 4 hours or overnight until set.
4. Make the Fresh Strawberry Coulis: While the posset chills, place 1 cup (150 g) hulled and quartered strawberries, 2 tablespoons (25 g) sugar, and 1 teaspoon (5 ml) lemon juice into a blender or food processor. Pulse until smooth. Taste and adjust sweetness if needed.
5. Strain the coulis through a sieve for an extra smooth texture or leave as is for a rustic feel. Refrigerate until ready to serve.
6. Prepare the Easy Shortbread: Preheat your oven to 325°F (165°C). In a mixing bowl, cream together 1/2 cup (113 g) softened unsalted butter and 1/3 cup (40 g) powdered sugar until light and fluffy.
7. Mix in 1 teaspoon (5 ml) vanilla extract and a pinch of salt. Gradually add 1 cup (120 g) all-purpose flour, stirring until the dough comes together.
8. Press the dough evenly into a parchment-lined 8×8-inch (20×20 cm) baking pan. Prick the surface lightly with a fork to prevent bubbling.
9. Bake for 18-20 minutes or until the edges turn golden. Let cool completely before cutting into small squares or fingers.
10. Assemble and Serve: Spoon a generous layer of fresh strawberry coulis over each chilled lemon posset. Add a piece or two of the shortbread on the side for a delightful contrast of textures.

Pro tip: The lemon posset should be set but still delicate to the touch. If it’s too soft, give it more chill time. If shortbread edges brown too quickly, tent with foil halfway through baking.

Cooking Tips & Techniques for the Perfect Lemon Posset

One of the trickiest parts is heating the cream to the right temperature. You want it hot enough to dissolve the sugar and gently start thickening but not boiling hard—that can cause graininess. Stir constantly and watch closely.

Straining the mixture after adding lemon juice is essential. It catches zest bits and any coagulated cream, resulting in a smooth, velvety dessert.

For the strawberry coulis, ripe berries make all the difference. If your strawberries are a bit tart, add a touch more sugar. I learned the hard way that skipping the sieve can leave unpleasant seeds or lumps.

Baking shortbread low and slow is key. It should be pale golden, not brown, to keep that tender crumb. Press the dough firmly and evenly for consistent baking.

Timing-wise, start the posset first since it needs several hours to chill. While it sets, make the coulis and bake shortbread so everything comes together seamlessly. Multitasking here saves stress—and trust me, it’s worth it.

Variations & Adaptations to Suit Your Taste

This recipe is pretty flexible and lends itself well to tweaks:

• Dietary: Swap heavy cream for coconut cream to make this dairy-free. Use almond or gluten-free flour blend for shortbread to accommodate gluten sensitivities.
• Seasonal: In fall or winter, try swapping strawberry coulis for warm spiced apple compote or roasted berry sauce. Fresh raspberries or blueberries also work wonderfully.
• Flavor twists: Add a splash of limoncello or elderflower liqueur to the lemon posset for a grown-up touch. For the shortbread, fold in finely chopped rosemary or lavender for herbal notes.
• Cooking methods: If you’re short on time, use store-bought shortbread or even vanilla wafers to serve alongside. The posset can also be made in larger ramekins for a more formal presentation.

Personally, I once made a batch with a hint of ginger in the strawberry coulis—it was a lovely surprise that added warmth without overpowering the lemon. Feel free to experiment and make this dessert your own.

Serving & Storage Suggestions

This lemon posset is best served chilled, straight from the fridge, allowing the creamy texture to shine with the fresh coulis on top. I like to present it in clear glass ramekins so the layers show through—it adds a bit of elegance without fuss.

Pair it with a light sparkling wine, like prosecco, or a cup of Earl Grey tea to complement the citrus notes.

Store leftover posset covered in the refrigerator for up to 3 days. The flavors meld beautifully over time, but the shortbread is best kept separate to maintain its crispness.

If you want to prepare ahead, bake the shortbread up to 3 days in advance and keep it in an airtight container at room temperature. Reheat briefly in a warm oven (300°F/150°C) if you prefer it warm and soft.

Reheating the posset isn’t recommended since it’s meant to be a chilled dessert, but you can refresh the coulis with a quick stir if it thickens too much in the fridge.
