Today’s recipe features Perfect Lemon Posset Tarts, which are remarkably easy to make. Posset, a rich and silky smooth dessert derives in the 19th century from an earlier drink. The posset with citrus and cream and is reminiscent of syllabub.

I use the tart cases from a previous post, Pâte Sucrée – Sweet Tart Cases. But you. can use shop-bought mini tart cases if you prefer. The recipe is uncomplicated, requiring only cream, lemon juice, zest, and sugar. Optionally, you can add berries on top as the posset sets.

Although the preparation is simple, there is some resting time in the fridge to allow the posset to set. That provides the thick silkiness characteristic of posset. Due to its richness, small portions are recommended. This recipe provides enough posset to accommodate 14 of my tart cases, but it’s flexible. In my video I use just 6 and also a large tart case. Any leftover posset can be set in small ramekins or glasses and served as is.
