Gorgonzola . . .

Gorgonzola with pears and walnuts on arugula is one of my favorite salads to serve in the fall.   My problem has been finding a gorgonzola that tastes like the cheese I buy in Firenze.  Finally, something close, but it goes by the name, "Blue Castello."  I bought it at Trader Joe's, and I've also seen it at Baron's.
