Mostarda is a sweet-savory dried fruit compote or chutney spice with savory spices (mainly mustard seed), which you can purchase at many specialty food stores
Cut the loaf lengthwise into 1/2-inch slices and place slices of the aged cheddar in between, building 2 large grilled cheese sandwiches.
Place the sandwiches directly into a panini press or side by side in a large non-stick pan. The bread has enough butter that you won't need to butter it. Toast on both sides over medium-low heat, until bread is golden and cheese starts to ooze.
Place sandwiches on a cutting board and cut into smaller pieces. Smear the tops of the sandwiches with Mostarda.
