Lemon Posset is a lusciously creamy, citrus-kissed British dessert made from just three core ingredients: cream, sugar, and lemon juice. The acid in the lemon naturally sets the cream, creating a silky, spoonable custard — no gelatin or eggs required. Paired with buttery shortbread cookies, it’s the perfect balance of tart, sweet, and rich.
