Tuiles are traditionally a French wafer biscuit served with a dessert but the word tuile is now used to describe any crispy part of a dish, be it sweet or savoury. Often now made with isomalt (a type of sugar) to ensure a good snap, the first tuiles were a thin biscuit made of flour, eggs and sugar, sometimes with the addition of almond meal. The mix would be spread thinly onto a baking mat, baked until golden brown and folded over a rolling pin whilst still warm to form the traditional curved shape.
