Mix together all the ingredients for the remoulade (mayonnaise, pickled cucumbers/cornichons, capers, parsley, lemon juice, mustard and curry powder). Spoon a little on top of each slice then top with some slices of cornichon and/or lemon and parsley as you wish.
Lightly butter all of the slices of rye bread.
For roast beef - lay slices of beef in slightly overlapping layers on two of the slices of bread. Drizzle some of the remoulade on top. Garnish with pickle slices/cornichons and some pea shoots.
For smoked salmon/gravlax - layer slices of smoked salmon over two more slices of bread, either slightly overlapping or in small folds. Top with a slice of lemon and a piece of dill as garnish (you can also add some remoulade, if you like).
For egg - slice the hard boiled egg and place a few slices on each of the remaining two slices of bread. Add slices of cucumber and radish around or on top of the egg in a pattern, as works with the egg slices. Garnish with some remoulade and pea shoots or dill.
