Inside out grilled cheese sandwich

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

Put the cheese inside the sandwich and flip the top slice over, then scatter grated cheddar on top of that hot face so the heat melts it slightly.

Add a little more butter to the pan, flip the sandwich so the cheese side is down and put about a tablespoon of grated cheese on the new top face.

Toast slowly on medium low, about three or four minutes a side, so the outside cheese gets crispy and caramelized without burning.
