Lemon Posset with shortbread
(Makes 6 x 150ml glasses)
For the posset
— 650ml double cream
— 150g caster sugar
— Grated zest and 100g juice of unwaxed lemons
For the butter shortbread
— 255g plain flour, sifted
— 170g salted butter, diced and kept cold
— 125g caster sugar, plus extra to dust
— Preheat the oven to 160°C/fan 140°C/gas mark 3. Heat the cream and sugar to scalding point, not boiling, in a small saucepan. While still on the heat, whisk in the lemon zest and juice and bring to the boil for 30 seconds, whisking all the time.
— Remove the pan from the heat and put to one side for the posset mixture to cool. When cool, pour into small (150ml) glasses, then refrigerate until set. This should take around 30 minutes.
— To make the shortbread, whizz the flour, butter and caster sugar together in a food processor, until the mixture comes together. Alternatively you can do this with your hands by rubbing the mixture together between your fingertips and then lightly pressing it together to form a ball – don’t overwork the dough at this stage. Turn out on to a sheet of non-stick greaseproof paper and roll out to ½cm thick using a floured rolling pin. Using a 5cm round pastry cutter, cut out rounds of dough and carefully transfer to a baking sheet lined with more greaseproof paper. Sprinkle with some extra caster sugar and bake in the preheated oven for 10–15 minutes or until lightly golden. Once out of the oven allow the shortbread rounds to rest for 10 minutes.
— Serve the posset chilled, accompanied by the shortbread.
