Three-Ingredient Lemon Posset Brûlée in Real Lemon Shells Tips, FAQ & printable recipe

Tips for success

To get the most juice from your lemons, roll them firmly against the countertop with the palm of your hand before cutting them. This breaks down the internal membranes and releases more liquid. For the zest, use a microplane to get only the yellow part of the peel, as the white pith is bitter and can negatively affect the flavor of your posset.

If the posset seems like it is not setting, ensure your refrigerator temperature is actually at 38 degrees Fahrenheit. A warmer fridge will significantly delay the setting process.

If you are in a rush, you can place the shells in the freezer for 30 minutes, but be careful not to leave them long enough to freeze solid, as this will change the creamy texture of the dairy once it thaws.

Variations

• Lime Posset Brûlée: Replace the lemons with limes for a sharper, more vibrant citrus flavor. Follow the exact same ratio of juice and zest. The green shells provide a striking color contrast when served on a white dessert plate.
• Orange and Vanilla Posset: Use oranges instead of lemons for a sweeter, milder flavor profile. Add one teaspoon of pure vanilla bean paste to the cream while it simmers to complement the floral notes of the orange zest.

Storage and make-ahead

Fridge

Store in the refrigerator for up to 2 days, covered loosely with plastic wrap to maintain freshness and prevent odor absorption.

Reheat

This dessert is intended to be served cold and should not be reheated, as the cream will lose its structure and melt into a liquid state.

Keep the finished, un-torched possets in the refrigerator for up to two days. Cover them loosely with plastic wrap to prevent them from absorbing other food odors in the fridge. The sugar crust should only be applied immediately before serving, as the moisture from the posset will cause the crispy caramel to dissolve and become sticky if left to sit for more than a few minutes.

This is an ideal make-ahead dessert. You can prepare the posset base and chill it in the lemon shells up to 48 hours before you plan to serve it. The flavor actually improves slightly as it sits, allowing the lemon zest to infuse the cream.

Simply keep them stored in the refrigerator until the very moment you are ready to add the sugar and torch them for that final, dramatic presentation.

Serving ideas

Serve the lemon posset brûlée on a small dessert plate, perhaps garnished with a fresh mint leaf or a thin slice of candied lemon to enhance the visual appeal.

Provide guests with small teaspoons so they can easily break through the hardened sugar crust to reach the velvety cream below. It is a rich dessert, so smaller lemons are often preferred to ensure the portion size is just right for a single serving.

If you want to create a more formal presentation, you can serve these alongside a small shortbread cookie or a almond biscotti. The buttery, crumbly texture of a cookie pairs perfectly with the smooth, citrusy cream.

Ensure the posset is served cold, as the contrast between the cold cream and the warm, freshly torched sugar is the highlight of the eating experience. Do not let them sit out on the table for too long before serving.

Three-Ingredient Lemon Posset Brûlée in Real Lemon Shells

Prep 15 minCook 3 minRest 3 hTotal 3 h 18 minServes 6

Ingredients

• 400 ml heavy cream
• 120 g caster sugar
• 90 ml fresh lemon juice
• 2 whole lemon zest
• 3 tbsp caster sugar for topping

Instructions

1. Cut the lemons in half and carefully scoop out the pulp to create clean shells. In a saucepan, combine the heavy cream and 120 grams of sugar. Bring the mixture to a gentle simmer over medium heat and cook for 3 minutes, stirring constantly to ensure the sugar is fully dissolved.
2. Remove the saucepan from the heat. Immediately whisk in the fresh lemon juice and the zest of two lemons until the mixture begins to thicken slightly. Pour the warm liquid evenly into the prepared hollowed-out lemon shells, filling them nearly to the rim without overflowing.
3. Transfer the lemon shells to the refrigerator and chill at 38 degrees Fahrenheit for at least 3 hours until the posset is set firm. Just before serving, sprinkle an even layer of caster sugar over the top of each chilled posset. Use a kitchen torch to melt and caramelize the sugar until it forms a deep amber, crispy crust.
