For the grape & buckwheat sizzle :
Wash and dry the grapes, and remove the seeds. Melt the butter in a hot pan, add the grapes, sprinkle with sugar and cinnamon, and stir. Cook until slightly browned. Remove from the pan and leave the fruit to cool.
For the raspberry tuile biscuit :
Preheat your oven to 160°C (th. 5). In a bowl, mix the melted butter with the caster sugar, add the raspberry coulis and flour. Whisk together until combined.
On a baking tray covered in paper, pour well-spaced-out circles of batter. Bake for 12 to 15 minutes, remove from the oven and leave the biscuits to cool (to give them a rounded shape, drape them over a rolling pin while they cool).
Sprinkle the Marie Morin caramel shards over the crème brûlées, caramelise on the surface using a blowtorch. Add a few grapes and buckwheat grains, and serve with a raspberry tuile biscuit.
You can replace the raspberry biscuit with an orange-flavoured one. The recipe can be found along with our morello cherry clafoutis.
