Equipment

Ingredients

  • 1 cup heavy cream
  • 2 tablespoons sugar
  • 2 tablespoons lime juice
  • ¼ teaspoon vanilla extract
  • ¼ teaspoon lime zest (optional)
US - Metric

Instructions

  • Add the cream and sugar to a 1-quart saucepan and place it over medium heat. Stir until the sugar fully dissolves. Bring the mixture to a vigorous simmer and cook for 8 to 12 minutes, stirring occasionally.
  • Remove the pan from the heat. Stir in the lime juice, vanilla, and lime zest. The mixture should look slightly thicker and reduced.
  • Let the mixture sit for about 5 minutes, stirring gently once or twice.
  • Pour the mixture into a ramekin or dessert dish. Refrigerate for 3 to 4 hours, or until fully set.

Notes

    • Use Full-Fat Cream: Heavy cream or heavy whipping cream with at least 36% milk fat is essential. Lower-fat cream or milk will not thicken properly.
    • Maintain a Vigorous Simmer: The cream should simmer with steady small bubbles and light steam. Avoid a rolling boil, which can affect the texture.
    • Add Lime Juice After Heating: Always stir the lime juice in after removing the pan from the heat. The acidity reacts with the hot cream and helps the posset thicken.
    • Chill Until Fully Set: Refrigerate the posset for at least 3 to 4 hours so it sets to a smooth, custard-like texture.
    • Make Ahead: Lime posset can be made a day in advance. Cover and refrigerate for up to 2 days.
     
    Important Note: Posset is simple to make, but the cream must simmer correctly for it to set properly. Keep the cream and sugar at a vigorous simmer with steady small bubbles and light steam rising from the surface. Do not let the mixture reach a rolling boil, which produces large bubbles and rapid boiling. Maintaining a steady simmer helps the posset thicken and develop its smooth, creamy texture.
