Lemon Posset

This elegant Lemon Posset is a classic British dessert made with just three simple ingredients—cream, sugar, and fresh lemon juice. The citrus naturally sets the cream into a silky, custard-like texture without eggs or gelatin, creating a luxurious, foolproof dessert.

Ingredients
  

  • 2 cups heavy whipping cream (36–40% fat)
  • 0.66 cup granulated sugar
  • 5 tbsp fresh lemon juice

Instructions
 

  • In a medium saucepan, combine heavy cream and sugar. Heat over medium-high, stirring until sugar fully dissolves.
  • Bring mixture to a full rolling boil, then reduce heat and simmer for exactly 5 minutes, stirring occasionally.
  • Remove from heat and immediately whisk in fresh lemon juice for 30 seconds until fully incorporated.
  • Let mixture cool at room temperature for 15 minutes.
  • Strain through a fine-mesh sieve into a measuring cup for a smooth texture.

Notes

Use only heavy cream (36–40% fat) and fresh lemon juice for proper setting. Chill thoroughly for at least 4 hours for the best texture, and always strain for a perfectly smooth, restaurant-quality finish.
