What Is A Posset?

A posset is traditionally made with cream, sugar, and citrus juice. The magic happens when the acid in the citrus juice reacts with the cream, thickening it to create a smooth, velvety texture. Our single serving Lime Posset stands out because it’s tailored for one person, making it ideal for an easy yet sophisticated treat. Adding a splash of vanilla enhances the flavor, making this posset uniquely delightful.

Ingredients

  • Heavy cream: Use either heavy cream (also known as double cream) or heavy whipping cream for this recipe. Both contain over 36% milk fat and are largely interchangeable, differing mainly in branding. Avoid lower-fat milks as they won’t work in this context. If you need a dairy-free option, coconut cream is a suitable substitute.
  • Sugar: Granulated sugar is used in a modest amount to sweeten the posset just right. If you prefer natural sweeteners, both honey and maple syrup are excellent alternatives.
  • Lime juice: Freshly squeezed lime juice is ideal for the best flavor, but bottled lime juice works in a pinch. Feel free to experiment with other citrus juices like lemon or orange for a different twist.
  • Lime zest: Adding a bit of lime zest can greatly enhance the lime flavor. While this ingredient is optional, it’s highly recommended for an extra zesty touch.
  • Vanilla: A touch of vanilla extract is used to add depth and complexity to the flavor profile of the posset.

How To Make A Lime Posset

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

  1. In a small saucepan, mix cream and sugar over medium heat. Stir until the sugar dissolves, then bring the mixture to a vigorous simmer for 8-12 minutes.
  2. Take the pan off the heat. Add lime juice, vanilla, and lime zest. The mixture will have thickened and reduced a bit.
  3. Let the mixture sit for about 5 minutes, stirring gently.
  4. Pour the mixture into a 10-ounce ramekin and refrigerate for 3-4 hours to set.

Important Note: Although a posset is simple to make with just a few ingredients, it’s crucial to adhere to the instructions precisely. Pay special attention when simmering the cream and sugar mixture. Aim for a vigorous simmer, characterized by noticeable movement in the cream, wisps of steam, and numerous small bubbles. Avoid letting the mixture reach a rolling boil, which is indicated by larger bubbles and more intense activity in the pot. By maintaining the simmer as described, you’ll achieve the perfect consistency for your posset.

Expert Tips

Serving Suggestions

  • Fruity: Fold in some fresh berries or chopped fruit for a burst of flavor and texture.
  • Crunchy: Sprinkle some chopped nuts or granola on top for added texture.
