I have a mac and cheese recipe that calls for 2 c. gruyere. I don't have many great cheese purveyors where I live and the only gruyere my store carries is $19.99/lb. I really didn't want to spend $10 on the cheese alone for this dish. Can I substitute Jarlesburg or another Swiss-type cheese here? Any thoughts about a lower priced, similar tasting and behaving cheese to the gruyere?
