Inside-out grilled cheese sandwich

Melt butter in a non-stick pan rather than spreading cold butter on the bread.

Build the sandwich with grated extra sharp cheddar inside; flip the top slice and put grated cheddar on its hot buttered side.

Add a little more butter, flip cheese-side down, and put about a tablespoon of grated cheese on the other side; toast slowly on medium-low 3 to 4 minutes per side until the outside cheese is crisp and caramelized, without burning.
