Indulge in a velvety single serving lime posset with a tangy twist! An easy, elegant dessert that’s refreshingly delicious and satisfying.

Craving a delightful, citrusy dessert but not looking to make a huge batch? This single serving Lime Posset is the perfect treat for you. Made without eggs or gelatin, this posset is incredibly smooth and rich.

What Is A Posset?

Posset is a creamy, pudding-like dessert that traditionally consists of just three ingredients: cream, sugar, and citrus juice. The acid in the citrus juice causes the cream to thicken, creating a luscious and velvety texture. We like to add a splash of pure vanilla extract which adds a wonderful flavor to our lime posset recipe.

The Origin And History Of Possets?

The term “posset” initially referred to a British hot drink made with milk curdled with wine or ale, often spiced, which was popular from the Middle Ages to the 19th century. However, over time, the recipe evolved into the sweet, creamy dessert that we are familiar with today.

Why This Recipe Works

  • Simple Ingredients: Cream, sugar, lime juice, and vanilla are all you need.
  • Quick Preparation: Takes just minutes to make and a few hours to set.
  • No Eggs or Gelatin: Naturally thickens without additional stabilizers.
  • Easily Customizable: Can be adjusted for different flavors and dietary needs.

Ingredient Notes

See the recipe box below for ingredient amounts and full recipe instructions.

  • Heavy cream: I recommend using heavy cream (double cream) or heavy whipping cream. Both of these ingredients are essentially the same – they both have over 36% milk fat, and the name often depends on the brand.  Lower-fat milks will not work but you can use coconut cream for a dairy-free alternative.
  • Sugar: A small amount of granulated sugar adds perfect sweetness. Honey or maple syrup can be used as a natural sweetener alternative.
  • Lime juice: Freshly squeezed lime juice is best, but you can use bottled juice if necessary. You can experiment with other citrus fruits like lemons or oranges.
  • Lime zest: A small amount of lime zest intensifies the lime flavor. This ingredient is optional but recommended.
  • Vanilla: For flavor.

How To Make A Lime Posset

  1. Combine 1 cup of heavy cream and 2 tablespoons of sugar in a small saucepan over medium heat. Slowly bring the mixture to a vigorous simmer, stirring until the sugar dissolves.
  2. After allowing the mixture to simmer for 8-12 minutes, remove the pan from the heat and stir in the lime juice, vanilla, and lime zest. You will notice that the mixture has thickened slightly and reduced.
  3. Stir gently and let the mixture steep for about 5 minutes.
  4. Pour into a little ramekin. Place the posset in the refrigerator to chill for at least for 3-4 hours.

Frequently Asked Questions

What Size Dishes Do You Use In This Posset Recipe?

For this lime posset, I use either a 10-ounce ramekin. For best results, use a dish of similar size.

Can I Use A Lower Fat Cream Or Milk?

No, you can’t. They don’t have enough fat to react with the acid to thicken this dessert.

Can I Reduce The Amount Of Sugar Used?

No. Sugar does more than sweeten this dessert. It also helps to create a lovely silky texture and balances the tart flavor of the lime juice.

Why Didn’t My Posset Set?

If you follow the directions in the recipe, your posset should set up perfectly. If if doesn’t, the mixture probably didn’t simmer long enough. You will notice as the cream and sugar simmer, the mixture slowly thickens and reduces slightly. After pouring the posset into a dessert dish, refrigerate for at least 3 hours.

Can I Make This Dessert Ahead?

Yes, it’s perfect for making ahead as it needs time to chill and set.

Is This Recipe Gluten-Free?

Yes, this posset recipe is naturally gluten-free.

Expert Tips

  • You can use another type of citrus in this recipe. Orange, grapefruit, or lemon would work the same way.
  • You can make this custard ahead of time. In fact, it should be refrigerated for 3 hours to set before eating. The custard will keep well for 2 days in the refrigerator.
  • Even though a posset requires just a few simple ingredients and is very easy to make, it is important that you follow the instructions carefully. The cream and sugar needs to simmer vigorously but be extra careful that the mixture does not boil. At a vigorous and rapid simmer, you will see a lot of movement in the cream. You will notice wisps of steam and quite a few bubbles but the bubbles will be small. Make sure the posset simmers like I have described. You do not want the cream to come up to a rolling boil which will look like bigger bubbles and lots of activity in the pot.
