For the best texture, keep the filo pastry covered with a slightly damp tea towel while working to prevent it from drying out and cracking.
Serve with a classic potato salad: boil potatoes until tender, drain, and toss with chopped onion and sour cream while still warm.
Ensure the beef is thoroughly chilled before wrapping to prevent the pastry from becoming soggy during baking.
This dish can be prepared ahead of time; wrap the beef and refrigerate until ready to bake.
