Slice the sourdough bread very thinly and spread with a little butter. Place thinly sliced Comte cheese on one slice and a spoonful of good fruit chutney on another slice. Season with a little salt and pepper and sandwich together.
Heat a heavy bottomed frying pan or a skillet or sandwich press. Melt a little butter inside it and add the sandwich. Toast until the bread is golden on both sides and the cheese has melted.
Transfer the sandwich to a hard board and bush it lightly with the garlic if using. Serve on a plate.
