🍋 How to Make Lemon Posset

Step 1 – Prepare the Lemon Shells

Wash the lemons well and slice each one in half lengthwise. Carefully scoop out the flesh, leaving the shells intact. Squeeze the removed lemon flesh, strain the juice, and measure ⅓ cup for the recipe.

⚡ Flash Tip: Thick-skinned lemons make the best serving cups because they're sturdier and less likely to tear.

🚫 Avoid This Mistake: Don't scrape too deeply or you may puncture the shell.

ALT: Hollowed lemon halves prepared as serving cups for homemade lemon posset.

---

Step 2 – Heat the Cream

Combine the heavy cream, sugar, and lemon zest in a medium saucepan. Cook over medium heat, stirring until the sugar completely dissolves. Bring the mixture to a gentle boil and let it simmer for 2–3 minutes, stirring occasionally.

⚡ Flash Tip: Watch the cream closely once it starts simmering—it can rise quickly.

🚫 Avoid This Mistake: Avoid a rolling boil, which can scorch the cream.

---

Step 3 – Add the Lemon Juice

Remove the saucepan from the heat. Stir in the vanilla extract, if using, followed by the freshly squeezed lemon juice. The mixture will begin to thicken almost immediately. Let it cool for 10–15 minutes.

⚡ Flash Tip: Fresh lemon juice produces the brightest flavor and helps the dessert set properly.

---

Step 4 – Strain the Mixture

Pour the mixture through a fine-mesh sieve into a clean bowl to remove the lemon zest and create an extra-smooth, silky texture.

⚡ Flash Tip: Straining gives the finished dessert a luxurious consistency.

---

Step 5 – Fill the Lemon Shells

Carefully pour the strained mixture into each prepared lemon shell until almost full.

⚡ Flash Tip: Using a measuring cup with a pouring spout makes this step much easier.

🚫 Avoid This Mistake: Leave a little room at the top to prevent spills when moving the lemons.

---

Step 6 – Chill Until Set

Arrange the filled lemon halves on a tray or plate and refrigerate for 2–3 hours, or overnight for the best texture.

⚡ Flash Tip: Chilling overnight creates an even firmer, creamier dessert.

---

Step 7 – Garnish and Serve

Serve the Lemon Posset well chilled. Garnish with fresh berries, mint leaves, or a little extra lemon zest just before serving for an elegant finishing touch.

⚡ Flash Tip: Garnish immediately before serving to keep everything fresh and vibrant.
