Lemon and Raspberry Posset Recipe

Lemon posset is one of the easiest, most foolproof desserts out there. It contains 3 ingredients: lemons, cream and sugar. Bam! It’s that simple. I’ve added rosemary to my shortbread, as its piney aromatic flavour perfumes the biscuits and goes amazingly with the lemon. The shortbread is a little different from traditional recipes as it uses corn flour and icing sugar for an extra ‘short’ and crumbly texture.


Top tip: make this pud the day before! The posset chills in the fridge, and so does the shortbread dough, so all you’d need to do on the day is bake the biscuits.

Extra tip: you can use any chopped ‘hard’ herb in shortbread. If you like the rosemary, next time try thyme or even sage.
