Ham Sandwich

Cream together the butter, mustard and sliced scallions. Season to taste with salt and freshly milled black pepper.

Spread one side of each slice of bread with the butter.

Cover each side of half of the bread slices with a layer of the thinly sliced ham.

Sprinkle over the parmesan shavings and season with a little freshly milled black pepper.

Lay a slice of buttered bread over the top of each sandwich and press down lightly.

Trim the crusts off each sandwich.

Now cut them into either 3 rectangles, 4 triangles, 4 squares or 4 octagonals (squares with the corners trimmed off).

Arrange the sandwiches neatly on a serving platter and garnish lightly with sprigs of watercress. Serve immediately.
