Coca de vidre is a product that can be found practically in any bakery and confectionery of the Vallès Occidental region. It is a thin, crispy and very oblong pastry of such a characteristic smooth and brilliant aspect similar to varnish and glass.
In order to obtain this aspect, a layer of sugar is added to the dough and then it is baked at very high temperatures. Once this process is finished, some anise is spread on the dough surface and it is possible to put some pine nuts on it too.
It is common to eat it in the afternoon or during breakfast and it is possible to eat it with some chocolate as well.
