Step 1 Evenly spread the Nutella over 4 slices of the brioche. Top with the remaining slices of brioche. Step 2 Whisk the eggs, milk and vanilla seeds in a mixing bowl. Dip the brioche sandwiches into the egg mixture and leave to soak for 2 minutes. Step 3 Melt 40g of butter in a frypan over a medium heat. When the butter starts to bubble add one brioche sandwich. Cook for about 2 minutes each side, until golden brown. Repeat with the remaining sandwiches, using 40g of butter each time. Step 4 Meanwhile, slice the bananas lengthways, leaving the skin on. Place cut side up onto a baking tray. Sprinkle the cut surface with sugar and use a kitchen blow torch to brûlée the sugar until it melts and caramelises. Alternatively, place the bananas under a hot grill for about 6 minutes. Step 5 To serve, place french toast onto serving plates alongside half a brûléed banana. Top with chopped pistachios, a drizzle of maple syrup and a scoop of vanilla ice-cream. Garnish with edible flowers and add raspberries, if using.
