3. Bring to the boil, stirring then drop the heat and simmer, still stirring for a coupe of minutes. Remove from the heat.
4. Whisk the egg yolks in a bowl then whisk in a tablespoonful of the milk mixture. Repeat three times then pout the combined egg and milk mixture into the warmed milk.
5. Set the pan back over low heat, and whisk until the custard thickens and is perfectly smooth. Don’t let it boil. Remove from the heat, and whisk in 2 tablespoon of the sugar and half of the limoncello. Set aside to cool.

For The Lemon Berry Sauce

1. Mix the lemon curd with 1 tbsp of just boiled water until runny and pour into the base of a medium baking dish.
2. Scatter the berries over the curd then press them down with a potato masher to flatten them down a bit and get their juices running.

4. Poor the cooled custard over the biscuits, straining if it is lumpy.

For The Meringue
