What Is A Posset?

A posset is an old-fashioned English dessert which has the texture of a creamy mousse or pudding.

This egg-free “custard” comes together as if by magic by mixing together sugar, cream, and citrus juice. No eggs, gelatin, flour, or cornstarch are needed, the posset thickens without any of them.

You might be familiar with my Honey Lemon Posset and if you love it, then I know you you’ll absolutely love this Lime Posset too.

How Does A Posset Thicken?

It’s amazing and almost magical to see how a posset can thicken so easily.

You see, when you add an acid (citrus juice) to milk it causes the milk to sour or curdle (as it would when making paneer), but when you add an acid to cream, the effect is entirely different. Because cream has more fat and less water than milk, the texture becomes smooth and creamy.

In the case of this Lime Posset, the cream and sugar are heated together then combined with lime juice, a touch of vanilla, and a little lime zest. This is when the magic happens.

The sweetened liquid mysteriously turns into a soft, creamy, delicate custard.

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 simmer, stirring until the sugar has dissolved.
  2. After allowing the mixture to simmer for 2 minutes, remove the pan from the heat and stir in the lime juice, vanilla, and lime zest.
  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 4-5 hours.

For this Lime Posset, I use either a 6-ounce or an 8-ounce ramekin. For best results, use a dish of similar size.

    What a beautiful dessert and lime sounds like just the right flavor. A lime flavored pudding type of dessert is perfect.
