I found some genuine, bright orange and sharp cheddar in my local grocery store. I was looking forward to having some really tasty mac-and-cheese.
Instead, I made a discovery. One does not melt the cheddar in the microwave. It doesn't melt; it goes crispy and that doesn't melt, either.
Now I feel like Scarlett O'Hara: Tomorrow is another day. And I have more macaroni and more cheese left.
