This is done easily by wrapping and placing the beef rolls onto a rimmed plate, six in a row touching. (It’s a nicer presentation if the rolls are wrapped with the basil going in the same direction, shiny side out.) Place the rolls on the plate in such a manner that the basil leaf, where it meets, is halfway up the side of the roll. Putting them close together will hold the basil to the meat roll.
Put two skewers through the rolls, taking care that the skewers run right through the basil. The rim of the plate will act as a guide; just hold the rolls in place with one hand as the skewers are run through. Separate the rolls so there is a space between them of about a half an inch.
