Hungarian Jancsi Torta

There is nothing more treasured than an old family recipe, and this delicious one was created by the Hungarian great grandmother of wine writer Paul Lukacs (son of the famed Hungarian historian John Lukacs) and given to me by his wife, Marguerite Thomas. Since Marguerite is like a sister to me, and I am one-quarter Hungarian, I feel a personal attachment to it. The Jancsi (YAHNsee) is intensely chocolate and moist, with little specks of chocolate and a wonderful crunch from walnuts. Althoug
