How to make Lemon Posset

Ingredients:

  • 3 large lemons
  • 1 cup heavy cream
  • ⅓ cup sugar
  • ¼ teaspoon kosher salt
  • ½ tablespoon lemon zest
  • 2½ tablespoons lemon juice
  • 1 teaspoon vanilla extract

Directions:

  1. Begin by grating ½ tablespoon of zest from one lemon.
  2. Slice the remaining lemons in half lengthwise. Use a spoon to scoop out the insides of the lemons and juice them through a fine-mesh sieve.
  3. Measure out 2½ tablespoons of lemon juice and set the rest aside for another use.
  4. In a small saucepan, combine the heavy cream, sugar, salt, and lemon zest. Bring to a gentle simmer over medium-low heat.
  5. Continue to simmer, whisking occasionally, for about 5 minutes.
  6. Whisk in the lemon juice and the vanilla extract. Strain the mixture through a fine-mesh sieve to remove any solids.
  7. Evenly divide the mixture into the lemon halves.
  8. Cover each half with plastic wrap and refrigerate for at least 4 hours.
  9. When ready to serve, let the posset sit at room temperature for 5 to 10 minutes before enjoying.

How to serve Lemon Posset

Serve Lemon Posset in the lemon halves for a beautiful presentation. You can also spoon the posset into small bowls or dessert cups for easier serving. Garnish with additional lemon zest or fresh berries for an extra touch. It pairs wonderfully with a cup of tea or a refreshing drink.

How to store Lemon Posset

To store leftover Lemon Posset, cover it tightly with plastic wrap or transfer it to an airtight container. Keep it in the refrigerator where it will stay fresh for up to 3 days. If using lemon halves, make sure to store them in a way that keeps them from drying out.

Tips to make Lemon Posset

  • Ensure you use fresh lemons for the best flavor.
  • Be careful not to overheat the cream mixture; simmering gently is key.
  • Use a fine-mesh sieve for straining to get a smooth texture.
  • Adjust the amount of sugar according to your taste; you can use less if you prefer a tangier dessert.

Variation

For a twist on the classic recipe, consider adding other flavors such as lavender or berries. Simply infuse the cream with your desired flavor during the simmering process, or add a layer of fruit puree beneath the posset for an exciting mix of tastes.

FAQs

  1. Can I use bottled lemon juice instead of fresh?
    While fresh lemon juice is recommended for its vibrant flavor, bottled lemon juice can be used in a pinch.

  2. How can I make Lemon Posset dairy-free?
    You can substitute heavy cream with coconut cream or a dairy-free alternative.

  3. Can I freeze Lemon Posset?
    Freezing is not recommended as it may change the texture. It’s best enjoyed fresh from the refrigerator.
