The seasoning for these sandwiches is key. Use a splash of white wine vinegar with the cucumber and add a little ground white pepper to the cream-cheese mixture; the acidity heightens the flavor of the cucumber while the pepper provides a savoury edge to the cheese.





Mix together the cream cheese and dill in a small bowl and season with a little ground white pepper. Put the cucumber slices in another bowl with the vinegar.
Spread the cream cheese and dill mixture evenly over one side of the brown bread slices. Top with the cucumber slices.
Butter the remaining white bread and put a slice on top of each slice of brown bread.
Trim the crusts and cut each round into four fingers.
