Everyone has at least one in their circle of family and friends — a food-obsessed individual that not only knows the difference between Gianduja (an Italian hazelnut-chocolate spread) and Nduja (a spicy Italian sausage spread), but also knows the proper pronunciation and where to source them. Good thing the Bay Area is full of epicurean-rich shops that make finding these exquisite treats a piece of cake (or Gianduia torte!).
