Asiago, parmesan, gouda, and parmesano reggiano are my faves. Yum!!
If you get really good quality (but expensive
) cheese, you don't need to use much to get a lot of flavor. An 8oz. wedge of parmesano reggiano can be about $15, but it's strong and has killer flavor! If you finely grate 4oz. of it, you can get over a cup, so one wedge can be used for about 4 dishes if you're using it to flavor a casserole or something.
