Cut the brioche into slices, then lightly toast them.
Mix the yoghurt with the lemon curd, lemon zest, and a little lemon juice. Taste it. Add some honey or sugar to your liking. If you’re using whipped cream – whip it first lightly, until fluffy, then mix in the same ingredients.
Line a deep glass bowl or dish with a layer of the biros and spread some jam over them. Then pour over half of the sherry. Scatter the blueberries on top, then spread half of the lemon cream over it.
Repeat the layers of the toasted brioche, jam, sherry and lemon cream.
Put the dish in the fridge for 2-4 hours (covered).
Just before serving, garnish with lemon zest.
