Line a small 8 1/2- by 2 1/2-inch loaf pan or terrine pan with plastic wrap so that plastic extends over edges.
In a small bowl, combine salt, cumin, cardamom, pepper, and sugar; set aside.
In a non-stick frying pan over low heat, heat olive oil; add walnuts and saute about 3 to 4 minutes or until light brown, stirring constantly.

Stir in green onions and brandy or cognac. Spoon 1/3 of cheese mixture into bottom of lined loaf pan, spreading evenly. Sprinkle 1/3 of remaining crumbled blue cheese evenly over cheese mixture. Sprinkle 1/3 of walnuts over blue cheese. Sprinkle with 1/3 of herb mixture. Repeat layering. Spread remaining cheese mixture evenly over top. Fold plastic wrap over cheese to cover. Refrigerate overnight.
