Method
1. To make the lemon posset, put the lemon zest and juice into a medium saucepan and bring to the boil. Set aside.
2. Put the cream and sugar in a saucepan and bring to the boil. Remove from the heat and mix in the lemon mixture that you’ve just made, then pass it through a fine sieve into a jug. Divide the posset equally between four decorative glasses and refrigerate for 45 minutes or until set.
3. To make the blueberry compote, put all the ingredients into a small pan and heat gently. Transfer to a bowl, cool, then place in the fridge.
4. To make the madeleines, scrape the seeds from the vanilla pod using the tip of a round-bladed knife and place in a saucepan. Drop in the vanilla pod, too, then add the milk, butter and lemon zest and juice. Heat gently to melt the butter – don’t allow the mixture to boil.
5. Whisk the egg and sugar in a bowl. In a separate bowl, combine the flour and baking powder. Add the egg mixture to the flour and whisk.
6. Pass the melted butter mixture through a sieve, and gradually beat into the egg mixture. Cover then chill for at least 30 minutes.
7. Preheat the oven to 180ºC/160ºC fan oven/gas mark 4. Grease the madeleine mould with butter and spoon the mixture into each hole to three-quarters full. Bake for 5–8 minutes until the tops spring back when touched. Use a palette knife to carefully remove them from the mould.
8. To assemble the dessert, spoon some blueberry compote over the top of each lemon posset, place a couple of madeleines on top and serve.
