Peel and thinly slice one half of an english cucumber

Put a paper towel on a large plate, and lay the cucumber slices in a single layer.

Lightly salt the slices and let them sit for 30 minutes. Check for flavor when finished, can rinse lightly if necessary and pat dry.

Gently pat the cucumber slices with another paper towel or clean towel to wick up the extra moisture.

Lightly pepper the slices.

Generously butter each slice of bread

Lay cucumber slices on half the slices of bread. Lightly salt again if desired.

Place the other buttered slices of bread on the cucumbers. Gently press the sandwich down and make a firm cut on the diagonal, or in squares.
