Mix the icing sugar, flour and the sesame seeds with the melted butter and the orange juice. Reserve in the fridge.
Preheat the oven to 200°C.
Remove the tuile mixture from the fridge and spoon the mixture on to a silicone baking sheet. Make sure to leave enough space between each tuile as they will spread out as they cook. Transfer to the oven and cook for 5 minutes. Remove from the oven and allow to cool before shaping the tuiles as desired.
«These tuiles are best enjoyed immediately after cooking but can be kept for a day or two in an airtight container.»
