El Xató is the most famous food of Vilanova, and all the Comarca del Garraf. Each town (in fact each chef) has its own recipe, but basically it is a mix of "cabell d'àngel" curly endives, preserved cod and tuna, anchovies and olives. The character of this meal is its sauce (the "xatò"): special dried peppers (nyoras), almonds, hazelnuts, garlic and vinegar, everything mixed in the mortar with olive oil.
It is a typical plate of the carnival, when is accompanied with different omelettes, local sausages, etc. The meal ends with something sweet: the meringue dessert (be careful, after drinking a few glasses of the excellent local "cava", people tend to start "meringue wars"!!!)
There is even a "gastronomic route" of El Xató, and some popular events and festivals around it.
