Preheat the oven at 180˚C.
Mix the sugar with the milk. Sieve flour and add. Then, add the pistachio nuts and lastly the melted butter.
Place 1 spoon per tuille on a baking tray lined with baking paper. Smear the mixture out with a fork to make a thin round slab.
Bake the tuilles for approximately 10 minutes until golden-brown and until each piece has a crispy appearance. Carefully place each tuille over a dough roller with a spatula. Let cool down quickly. This must all happen very quickly.
