For neater slices, use a long, sharp knife and wipe the blade between cuts; if your tortillas are cracking, warm them briefly to make them more pliable. Adjust the filling amounts lightly—too much cucumber or onion can cause slipping and sogginess. Choose high-quality cold-smoked salmon for the best texture, and substitute spinach or whole-wheat tortillas if desired. The cream cheese mixture can be made a day ahead, and the assembled rolls can be wrapped and refrigerated up to 6 hours before slicing. Add a pinch of salt only after tasting, since smoked salmon and capers are already salty.
