Make a Simple Lemon Posset with 3 Ingredients

Make a simple lemon posset with only three ingredients; how is that possible? Madeline was home over the fourth of July and made it, and it was so good I wanted to make it for a little dinner party on the patio. It’s the perfect ending to a summer meal. It’s full of lemon flavor and tastes light, although it’s mostly heavy cream…sooooo, there’s that.

So, what is a posset?

A posset is a cold dessert made from thickened cream. It’s usually flavored with lemon. According to Merriam-Webster, the history of posset is a hot drink of sweetened and spiced milk curdled with wine. I can’t imagine curdled milk mixed with wine but lemon; that’s another story.

What is the difference between panna cotta and posset?

Panna cotta or American pudding recipes rely on cooking the cream and adding gelatin or flour to thicken the cream.

What thickens the lemon posset?

A posset allows the acid to do the work, although I can’t explain the science behind that process. But somehow it works. However, measuring the ingredients is crucial to get the right consistency.

The 3 Ingredients You Will Need to Make a Lemon Posset

  • Lemons (obviously)
  • Superfine sugar (or regular sugar that you blend in a food processor)
  • Heavy whipping cream

Special Equipment Needed for this Recipe

What we love about this lemon dessert and how to serve it

Nasturtium Flowers, Leaves, and Fresh Mint

We love a dessert that can be made ahead. It makes entertaining much more fun when you have the dessert made and cleaned up the day before a dinner party. The hands-on part of making this dessert is only about 10 minutes, including cleaning up!

It can be served in ramekins, cups, or right in the hollowed-out lemon. If you feel it needs more than just the posset, a couple of shortbread cookies would be perfect!

I added nasturtium flowers and leaves to add color and served on small vintage plates.

Lemon Posset is the perfect combination of creamy, tart, and sweet. It’s a surprisingly fresh and light dessert (although technically, there is really nothing light about it) that’s ideal for serving on warm summer nights. But it’s so good I could envision eating it on any given night throughout the year. 

  • Author: Annie Diamond
  • Prep Time: 10 minutes
  • Cook Time: 15 minutes
  • Total Time: 25 minutes
  • Yield: 7 1x

Ingredients

Scale
  • 24 Lemons (depending on if you are using them to serve inside the lemons)
  • 2/3 cup superfine sugar (I processed regular sugar in a small blender)
  • 2 cups heavy cream
  • Garnishes (you can serve plain, with a dusting of powdered sugar, edible flowers, or raspberries)

Instructions

  1. Gather your ingredients.
  2. Using a fine grater, zest both lemons. Cut the lemons in half, juice all four halves of the lemons, and remove any seeds. You should have approximately 1/2 cup of juice.
  3. If serving the posset in the lemons, remove all the fruit from each half of the lemons and discard, saving only the lemon cups.
  4. Pour the lemon juice into a small saucepan, add the lemon zest and superfine sugar, and stir until combined. Slowly bring the mixture to a very gentle simmer and cook for approximately 4 minutes until all the sugar has dissolved and the mixture becomes a little syrupy. Set it aside to cool.
  5. Pour the cream into a medium-sized saucepan. Bring the cream to a gentle boil and adjust the heat to low. Let it simmer for about 5 minutes. Remove from heat. Make sure to cook the cream slowly. It will spoil the cream if you’re impatient and try to boil it quickly.
  6. Slowly pour and whisk the lemon syrup into the hot cream using the same saucepan. Strain the mixture through a fine sieve into a measuring cup. Let it cool slightly.
  7. If serving the posset in the lemon cups: pour the mixture into each lemon half. 
  8. If serving the posset in ramekins: pour the mixture into the small ramekins.
  9. Place lemon cups or ramekins on a small tray or platter and bring them to room temperature. Cover with plastic wrap and refrigerate for at least 4 hours. They can be refrigerated overnight.
  10. To serve, remove from the refrigerator and let sit for at least 5 minutes before serving.
  11. Garnish the posset with berries, edible flowers, or a dusting of powdered sugar, and serve with small spoons.

  2. I enjoy your blog and the Lemon Posset recipe looked lovely, but when I tried to print it, advertisements blocked out part of the recipe.
    Is there a way to have a print version of a recipe with no ads?
    Thank you.

    1. Hi Susan!
      I am so sorry that the amounts were missing in the recipe card! I meant to go back and addd them and forgot! I have updated it now! Thank you for taking the time to let me know!
      I think to print the recipe without ads (I know….so annoying), it’s a setting when you go to print, you select options in the recipe card – This box is to the right of print. Then you can unclick the things you don’t want to print. Like images….etc.
      Hope this helps!
