What is "tuile"

n. A type of thin, papery cookie, often bent into fancy shapes

A tuile is a baked wafer, generally arced in shape, whether thin, crisp, sweet, or savory, that is made most often from dough (but also possibly from cheese), often served as an accompaniment of other dishes. Originally from France, 'tuile' is that language's word for tile, after the shape of roof tiles that the arced baked good most often resembles. Tuiles are commonly added as garnishes to desserts such as panna cotta or used as edible cups for sorbet or ice cream.
