Warm savory roast beef and salty pungent blue cheese give this grilled cheese its name; the purple-black, sweet and acidic Balsamic Onion Marmalade ties everything together. This is a grown-up grilled cheese and these are strong flavors, but so good together. If you don’t want to take the time to make the marmalade, you can substitute store-bought onion jam, but don’t skip it altogether- it takes this sandwich over the top.

The sharpness of blue cheeses can vary considerably; some are creamy and mild, some so sharp you can smell them across the room the minute they’re unwrapped. You may want to adjust the amount you add to this sandwich depending on the strength of the cheese you select as well as your own tastes.
