Instructions

Cut limes in half. Run a small paring knife or spoon around the inside edge to separate the flesh from the rind. 4 large limes
Use a spoon to gently scoop out the fruit segments and juice into a bowl.
Pat the inside dry with a paper towel to remove excess moisture
In a saucepan over medium heat, combine the heavy cream, sugar, and salt. Stir until the sugar dissolves. 2 cups (240 ml) heavy whipping cream ⅔ cup (134 g) granulated sugar Pinch of salt

Notes

Storage: Store covered in the fridge for up to 4 days. I do not recommend freezing.
Use Heavy Cream Only-Posset relies on the fat content in heavy cream to set properly. Do not substitute with milk or half-and-half, as they won’t thicken the same way.
Before the mixture reaches a simmer, ensure the sugar is completely dissolved to avoid a grainy texture.
Let the mixture gently simmer for 5 minutes—this thickens it slightly and helps it set later. Boiling too aggressively can cause the cream to separate.
Once you’ve simmered the cream, remove it from the heat before stirring in the citrus juice. If added while still boiling, the acid can cause the cream to curdle.
If you pour the posset into serving dishes while too hot, it might form condensation on top. Let it sit for 5 minutes before transferring to ramekins or citrus shells.
Posset needs time to set properly—overnight is even better for a firmer texture.
Let the posset cool to room temperature before placing it in the fridge and keep space around the dishes to ensure even chilling.
