Lemon or passion fruit posset is a refreshing, low-effort treat that requires no baking, eggs, or gelatin. The fruit's natural acidity thickens heavy cream into a silky, chilled custard—you will be amazed by the result.
Ingredients
500ml2 cups heavy cream
150g3/4 cup granulated sugar
120ml8 tablespoons lemon juice
1tablespoonlemon zest
Instructions
Zest the lemon: Zest 1 large lemon using a grater, removing only the bright yellow outer layer and avoiding the bitter white pith underneath.
Heat the cream mixture: In a saucepan, combine the heavy cream, sugar, and lemon zest. Bring to a boil over high heat, whisking constantly. Reduce the heat to medium and maintain a steady boil for 8 minutes, stirring constantly. Watch the mixture closely; if it starts to foam up, briefly remove the saucepan from the heat while continuing to stir. Keep boiling until the mixture reduces to 2 cups, which will give the posset the perfect consistency. Measure the mixture while it is still hot.
Strain the mixture: Remove the saucepan from the heat and pour the mixture through a fine-mesh strainer to remove the lemon zest.
Add the lemon juice: Stir in the lemon juice and whisk well to combine. Let the mixture cool for 5 minutes.
Chill the posset: Pour the lemon posset into ramekins. Let it cool completely at room temperature, then refrigerate for at least 4 hours before serving.
To make the passion fruit juice, cut the passion fruits in half and scoop out the pulp. Transfer it to a food mill or potato ricer. The holes in the mill or ricer are smaller than the passion fruit seeds, allowing the juice and pulp to pass through while leaving the seeds behind.Place the mill or potato ricer over a bowl and turn the crank or press the handles to extract the juice. Scrape any remaining juice from the bottom of the mill or ricer.Replace the lemon juice with passion fruit juice and omit the lemon zest. If desired, add a few passion fruit seeds to your passion fruit posset. They are edible, nutritious, and add a lovely contrast in texture.Watch the video tutorial below to see how it's done.
