Puttanesca sauce has the right balance of sweet from the tomato, savory and tangy from the olives, and spicy from the red pepper flakes. Originally from Naples, pasta puttanesca or aulive e chiapparielle in Napolitan (olives and capers in English) is now popular throughout Italy and worldwide thanks to its simplicity, beautiful colors, and, most importantly, its wonderfully rich and yet balanced taste.
