Preheat the oven to 375 degrees. (This is only to toast the bread; you can use a toaster oven instead if desired.)
Using a 1.1 ml round cutter, cut 20 circles. Or if you do not have round cutters, cut the bread slices into approximately 1 ½ inch (3.8 cm) squares, removing the crusts first if needed. You will need a total of 20 squares; depending on the size of your bread slices, this should take between 2 - 3 slices of bread.
Place the bread squares onto a small tray and bake in the preheated oven for 2 - 3 minutes. or until the squares of bread are toasted. Remove the toasted bread to a platter and set aside.
Place the room-temperature cream cheese in a small bowl. Mash the cream cheese with a fork until it's smooth.
Mince one Tbsp fresh dill and add to the cream cheese.
Add the lemon zest, salt and pepper, and mix well.
Spread the cream cheese on the toasted squares of bread. Or use a pipping bag to pipe it on.
Carefully tear off a small strip of the smoked salmon, roll it into a rose shape, and place it on top of one of the bread rounds. Continue this process until all of the bread are topped with smoked salmon.
Garnish each canapé with a few capers and a small sprig of dill. For best results, serve immediately. Or, if needed, loosely cover the serving tray with plastic wrap and place in the fridge for 1 - 2 hours before serving.
