In a small mixing bowl, combine cream cheese and cream. Beat at high speed with a mixer until light and fluffy. Reduce speed to medium, and add salmon, lemon zest, lemon juice, lime zest, lime juice, and pepper, beating until incorporated.
Transfer salmon mixture to a piping bag fitted with an open-star tip (Wilton #32). Pipe into phyllo cups in a decorative fashion.
Garnish with lemon and lime zest, if desired.
Notes
Make-Ahead Tip: Salmon mixture can be made a day ahead and stored in the refrigerator until needed. Let soften before using.
