Start by washing the cucumber thoroughly and slicing it into very thin rounds. Lightly sprinkle salt over the slices and let them sit for a few minutes to draw out excess moisture. Pat them dry with paper towels to avoid soggy sandwiches.
In a bowl, combine softened cream cheese, butter, dill, chives, lemon juice, salt, and pepper. Mix until smooth and creamy. The herbs should be evenly distributed, creating a flavorful and aromatic spread.
Take fresh bread slices and trim off the crusts for a classic tea sandwich look. Spread a thin, even layer of the herb mixture on each slice. Make sure to cover the entire surface to create a moisture barrier.
Layer the cucumber slices evenly over one slice of bread. Place another slice on top, spread side down, to form a sandwich. Press gently so everything holds together without squeezing out the filling.
Use a sharp knife to cut the sandwiches into triangles or small rectangles. Serve immediately for the best texture and freshness. These sandwiches are best enjoyed right after assembling.
