I didn't feel up for much cooking so I made another attempt at Alfredo sauce. I've been trying to make it with just the butter and freshly grated cheese (I used Pecorino Romano). I was really careful with the temperature of the butter, but the cheese just didn't "dissolve" very much. There were lots of little strings of the cheese, the way it was grated. There were two lumps. Maybe the butter wasn't hot enough this time. Oh well, the attempts sure taste good.
