Valle d'Aosta, northwestern Italy
Named for the curved roof tiles (tegole) they resemble, these wafer-thin biscuits are a signature of Valle d'Aosta confectionery. The batter is made from very finely ground toasted hazelnuts and almonds combined with icing sugar, egg whites and a trace of vanilla; no flour, no butter and no leavening. A thin layer is spread onto a silicone mat or well-buttered baking sheet using a small offset spatula, each disc about 8 cm in diameter. Baked at 180°C for 6–8 minutes until pale gold, they are removed immediately from the oven and draped over a rolling pin or curved mould while still pliable, setting into their characteristic curved shape within seconds.
Intensely nutty from toasted hazelnuts and almonds with a whisper of vanilla; texture is the point — paper-thin and shattering crisp.
{"Toast the nuts to deepen flavour but cool completely before grinding — warm nuts make a paste rather than a powder","Grind the nuts as finely as possible without releasing their oils: over-processing turns the mixture oily and the biscuits will spread unevenly","Spread the batter very thinly and uniformly — thick spots remain soft while thin edges burn","Work quickly after removing from oven: the draping window is under 20 seconds before the biscuits set rigid","Bake in small batches so all biscuits can be shaped before they cool"}
{"Store in an airtight tin with a silica gel packet — they will remain crisp for up to two weeks","A trace of orange zest in the batter complements the hazelnut and almond without dominating","They pair classically with fonduta or as an accompaniment to gelato and panna cotta"}
{"Using warm or freshly ground nuts — the released oil makes the batter greasy and the biscuits spread too thin or burn","Spreading the batter too thickly, producing a soft rather than crisp, wafer-thin result","Waiting too long before draping — once cool the biscuits crack when bent","Storing in humid conditions: these biscuits are highly hygroscopic and lose their snap within hours"}
