Mix the ground beef with the egg and all the seasonings. Let it marinate for 50 minutes to absorb the flavors.

Wash the betel leaves and pat them dry. Place a leaf on a cutting board, add a spoonful of the beef mixture, and roll it up. Repeat until all the filling is used.

Heat oil in a skillet. When the oil is hot, add the wrapped rolls and fry until evenly cooked. Remove and drain on paper towels, then serve on a plate with hot rice.
