The other day I posted pics of my lunch...a humble grilled cheese sandwich and Goldfish crackers. I just wanted to share a tip with you about how I "grilled" my grilled cheese. I use mayonaise. I know it sounds weird to use mayo instead of butter on the outside, but it is a fat after all and browns the bread beautifully. But I will say that it burns quite a bit more quickly than butter, so don't have the pan "screaming hot" (a la Rachel Ray), or your bread will burn. Grill it at a slightly lesser temp than you would use if you were using butter.
My husband of all people taught me this trick one day when I was complaining that I wanted a grilled cheese, but was out of butter. He said that his family always used mayonaise on the outside of their bread and then grilled it. I had never heard of such a thing and was so proud of him for being so clever!
So the next time you're out of butter, use mayo...it works!
